60MPx without IBIS - that's a big no-no for me. Not even considering 40MPx without IBIS, really. Then there is its price, as I said above.
In today's world ... IBIS is amazingly good on one hand. On the other hand, you kinda "don't need it".
Yes, I know that the amazing aspect of IBIS will let me hand hold my 500/5.6 down to 1/10 of second. That is radically sweet.
On the other hand, today's sensors are so good at higher ISO / invariant ISO processing that an ISO bump will let me keep my shutter speeds high enough that IBIS isn't necessary. Sure, going from 1/10 of second to 1/1000 of a second to get a 2X focal length on my 500mm is almost 7-stops. 7-stops is a bit outside of the range of sensors that have an adequate 5 stop PP invariance, and an excellent 3 stop PP invariance.
Which is why I shoot 500mm on my Leica SL ... with IBIS.
However, on my M10R (40mp), I'm not ever shooting my 500mm. My longest M-mount lens is 135/3.4 APO, which would dictate for a 2X FL a shutter of around 250 (270) with ease. Now, that vs. my (hypothetical need for 1/10) is between 4-5 stops. I'm in the window for PP. But, with good technique I can easily go with 1X around 1/125 for a 3-4 stop ISO bump.
But, how often do I actually use my 135 hand held. Not much, really. I mostly use it for landscape reach and put it on sticks. When I DO use it handheld, it is typically in decent light of Sunny 16 (EV15) to Dusk (EV 11) where ISO 125, nets me an f/4 at 1/2000 (4 stops aperture > 4 stops speed from Sunny 16 at ISO), down to (4 stops less) f/4 at 1/125 (i.e. 1X FL).
So, wrt to the need for IBIS ... my case use offers alternatives that don't make it "so restrictive" that I'd avoid 40mp, and adopt only 24mp because of no IBIS.
Bear in mind, what lenses are you actually going to be using on your M? Do you REALLY need IBIS. I mean, folks were shooting without IBIS for a very, very long time before IBIS came along. But, that was also BEFORE sensor had such excellent ISO latitude. At normal / wide focal lengths, the range of necessary shutter speeds (oh, btw ... the 24MP of the M240 is older sensor tech than the 40MP M10R, the M10R can tolerate the ISO bump, the M11 is now BSI, and tolerates well, too) wrt to IBIS for hand-holding is well within the range of handholding and a modest ISO bump when needed.
If you truly WANT 24MP (for whatever reasons) ... then, that's fine. BUT, the lack of IBIS (on an M rangefinder) would NOT be a dominant factor in my consideration for its use.
You say you want IBIS for shooting in low light ... i.e night street, well you still have lots of ISO latitude. But, then ... there is the prospect that if you DO drop your shutter down to speeds that are IBIS territory, you are now in subject motion blur territory (which may / may not be a concern), and that takes you back to bumping your ISO / shutter (or faster glass).
So, for me ... when using an M-mount rangefinder (vs. my SL2-S) or OIS in my Q2, I simply understand the "old school" ways of shooting, the range of FL's actually being used, the sensor tech and the PP tools available, alongside my use case for the M body, without IBIS.
IBIS is a sweeeet tool. BUT, for some it is a debilitating CRUTCH that keeps them from using their noodle about what they CAN do, while being hyper-focused on what they (think they) CAN'T do.
The M240 is sweet ... I like my M240-P (traded up for my M10R), and can recommend the P version (cost more, but the buffer difference, improved shutter release, level, etc. make the -P a bit more responsive to certain things). Still have my M246 (mono), alongside my M10R.
Here's another thing ... if you happen to be mono oriented, the base ISO on the M246 is essentially a built in ISO bump that the lack of IBIS isn't even much of a consideration, at all.
So, as to IBIS ... it does have its place. And you can certainly live without it. All it takes is a bit of "thinking" to recognize when / where / how life without IBIS functions. I mean, seriously ... how many decades of photographers before IBIS came along were making the images that we herald in high esteem. I dig on IBIS, but the lack of IBIS doesn't dictate which M body I use. Does the lack of autofocus, dictate which lens you use on your camera when using M-mount lenses? No, you accept the terms of manual focus only and harness it within that context of use. Zone focusing, muscle memory / tab focusing, dof, etc. Takes a bit different approach than simply pressing the shutter and letting the camera / lens do the focusing. But, it is not restrictive ... UNLESS, you restrict your MIND regarding how to use the tool to harness what it is vs. being focused on what it isn't.
IBIS ... sweet tech tool. Don't need it for everything ... think about it.

. And, actually, thinking got give a second chance to an M-240 (first one lasted for 6 months).
