But if the site doesn't reflow responsively - as in the case of old 
non-responsive fixed-width sites - all you'd get is horizontal 
scrolling. So I think designers are doing the right thing / browsers are 
doing the right thing...when the user zooms, the *effective* pixel width 
is reduced (zooming in simply scales up each pixel measure), and with 
responsive design authors can define how to best make use of that 
particular width/size of viewport.

What's really at issue is that authors should not completely omit 
content/functionality just because a viewport is smaller. It's a 
usability problem for all users, but disproportionately affects low 
vision users who may be using zoom functionality, so it's an 
accessibility issue?

So that would require all UAs to implement a different new zoom 
mechanism. In the meantime, authors would need to build some form of 
"zoom, but not responsively" mechanism into their sites? Not quite sure 
that'd be the best way forward, compared to a fairly straightforward 
"don't completely omit content/functionality at different breakpoints as 
it will affect all users and particularly LV users with zoom"
