For me this would still be to large for street work but I can see it's appeal for some. In my usage case the 35-150 is still the best event and even multi purpose portrait lens on the market They are branding this as the light version of the 35-150, but at f/2.8 I think the appeal is smaller.
I understand Tamron wants options; but between a 28-75, 35-100 or 35-150 I just don't think most people would pick this 35-100.
Is it less appealing than the 35-150? Maybe yes, maybe no. Depends on your use case, what level of size/weight you are prepared to accept given that use case, and what lens you would pair it with, and what alternative lens you could choose if not this.
For me, as a photographer who hovers between family snapshots and portraits, street and travel, low light, and events, if for whatever reason I am only allowed to bring one lens... the 35-150 (in either Tamron or Samyang flavour) would be my "cold dead hands" lens, for sure. For that kind of application, the 28-75 never excited me personally, I constantly felt I wanted to go wider and have always been happier with a 24-xx or even 20-xx as a normal zoom. Don't get me wrong, I love the Sony 28-70 F/2 (my other "cold dead hands" lens) but only because it also replaces a bunch of fast primes, which a 28-75 doesn't do.
However if I am on a business trip by myself, I would be self-conscious whipping out a 35-150 in business meetings or be lugging around a camera bag with my full kit on top of my work stuff, luggage at the airport etc. Indeed I have just come back from a trip with a TTArtisan 75/2 (on L-Mount paired with a Panasonic Lumix 18-40 kit lens) as a longer walkaround/candid street lens for those couple of hours downtime to wander around in the city after a day of meetings in a conference room. The TTArtisan was excellent and just perfect in terms of usability as an additional lens I could fit easily alongside my work laptop and papers. If I had brought my Sony system, I would have been equally happy with the Tamron 35-100 paired with a wider, compact lens, perhaps my Viltrox 20/2.8.
I think the same could be said of the Tamron 35-100 as an alternative to say a single 85/1.8 prime - not much weight gain (and no weight difference once you add in a second prime like a 50 or 55 F/1.8) but much much more flexibility compared to the prime.
On L-mount, and probably on E-mount as well, the 35-100 would make a fantastic and relatively lightweight video lens that allows you pull into a tighter framing than a 28-75.
One thing the 35-100 can definitely not do is replace a dedicated telezoom lens, unlike the 35-150. Once I got the 35-150, I sold all my 70-200 and 70-180 lenses and never looked back.
