Well...it might be because we're starting to see bikes designed to ONLY allow for 1X (see 3T Strada), and some might be worrying it's the next "road disc brake" or "thru axle" type push that although in the short term increases choice, eventually
decreases choice (see "26 inch MTB wheels/tires")...
I think you're reaching on this one. The analog you should draw is to the demise of the mountain bike front derailleur, which actually seems to have been a consumer-demand driven phenomenon that won out on the merits of the product offering, not by the push of industry. Choice was not diminished. SRAM bet on the XD driver with a 10T cog going up to 42T and Shimano bet on Synchroshift di2 tech. We know who won that one.
Well...don't forget that a BIG part of the push for 1X on MTBs was the fact that with 29er and 650B wheels becoming "vogue", it got harder and harder to just fit a front derailleur in there while trying to maintain reasonable geometries, especially on full suspension rigs. That, IMO was the biggest driver...everything else about that was just rationalizations ;-)

There is
one bike out there that doesn't have a mount for an FD hanger, but that also seems to be part of a specific strategy to shift the 1x paradigm to 12 speed or 13 speed drive train via a unicorn freehub body. The bet from 3T seems to be that a 10T with 12 and 13 speeds is the tipping point for 1x to go from a niche use case to widespread adoption, and putting these eggs in the XDR basket without larger industry players on board seems tantamount to Specialized's experimentation of the 135mm thru axle standard in the 2016 cx frames.
I'm not betting against 3T either, even though it's a ballsy move to be a first mover here. But in general, regarding the Strada and the removal of the FD hanger --
this was their logic:

The biggest new thinking is about the clutter around the crankset with water bottles, front derailleurs and two chainrings. All of that blocks wind and forces air to go wider, all the way out around the legs. Getting rid of the front derailleur and small chainring lets air flow around the seat tube, between it and the chainring, keeping it more streamlined against the bike.
I call bullshit. I want to see the test rig that determined that the front derailleur was pushing all that air around the legs, which is something different than rappstar is saying in this thread. Or are we in CFD la la land at this point? This goes back to what Heath was saying about how there's all this turbulent air down there, which probably renders any test data without pedaling legs next to useless.
Yeah...I'm pretty skeptical on that claim as well. I'm also skeptical that being able to include a FD mount would compromise the frame design somehow...especially after seeing the frame section in that location.
My guess is the REAL reason they wanted to go solely 1X on the Strada was to allow them to use a shorter chainstay length (405mm IIRC) than they otherwise could with a disc rear wheel. Without going 1X, they couldn't go that short without causing chainline issues...as evidenced by Specialized's "non standard" derailleur hanger and rear hub on their Tarmac Disc. AFAIK, both Shimano and SRAM do not recommend using their 2X setups on disc bikes with chainstays that short.

The only way it makes sense to remove the FD hanger on new gen aero bikes is to actually prove the above point (as relayed by Bikerumor) and to convince 2x-inclined consumers of it. Otherwise as a manufacturer, you eliminate choice and by extension reduce your potential customer base, which just won't make sense for most companies.
Yup, as I pointed out earlier...I think Specialized quickly learned how appealing (or not) a 1X only version of a bike was when they first came out with the Allez Sprint. A version with a FD hanger wasn't long in following...
