I think this is the rub where some folks are ready to embrace this ... while others are looking for every reason to fight it, tooth and nail.
Good to hear your 1/15s results ... pretty much inline with my expectations for a 35mm lens. 
I know the "rule of thumb" for some is 1:1 and others use 2:1 for extra caution ... but, I also know that with good technique I can get 1:2 results with glass wider than the format diagonal. Here, we have the 4:3 at 55mm, so a 35mm lens is wider, by a factor of roughly 0.65 (not quite 0.5), so the 1:2 isn't really a 2X factor difference from 1:1 rule of thumb. More like 1.3X better technique required than the 1:1 rule of thumb.
Long way of saying ... yup, 1/15s with a decent steady hand and mental technique / approach is a reasonable expectation for hand held, stabilization.
1/8 (which would then be a 2.6X factor vs. the 1:1 rule of thumb) is probably a stretch with a drop in keeper rate.
And, 1/15s with f/4 is around EV 8. Bumping to ISO 1600 is another 4EV, and lands you into 4 EV territory, ISO 3200 ... 3 EV, etc. Add in the fact that you can likely lift another 3 EV in post, ISO 3200, 1/15s, f/4 could get you into 0 EV territory. See video in next post at 8:45 where a +4 EV exposure is applied to ISO 1000, f/4, 1/60s. The video then goes into ISO 12800, f/4, 1/30s, and finally at ISO 100,000. Also, 1/20s, ISO 8000 at 12:40.
He follows that with the comment, regarding the effectiveness of the leaf shutter / shutter release to help facilitate better handholding performance than what folks might be used to with others (i.e. focal plane shutters).

The poster in the thread below shot 1/75's, ISO 3200, f/4 for a night scene. So, for those who aren't inclined toward 1/15s ... that's a couple stops diff, so maybe you're only good to 2 EV scenes handheld, etc.

While the lack of IBIS is a highly contentious point for plenty of folks. I think those who have the wherewithal to think it through, will find it to not be nearly as limiting (albeit, requiring a different degree of care) as some might suggest.

B&W shots are with the in camera ACROS with red filter or green filter film simulations applied. For those complaining about the lack of IBIS, I've consistently been getting sharp shots handheld at 1/15 sec without any problems. Just don't rush....slow down, use it like you would a Leica M and you'll be fine.
