Following up on this: Given that FireFox is the only browser that allows for Text-only zoom; that responsive design eliminates horizontal scrolling; and almost none of the sites I visited worked perfectly with 200% text-only zoom- Should text-only zoom still be a (high) concern?

I'd definitely urge everybody to put the focus on responsive design. Just scaling the text may cause all kinds of hard to avoid issues (and wouldn't a vision impaired user want to see icons and other such stuff enlarged at the same time?). Good responsive design ensure that when using zoom, all aspects are zoomed reasonably well in relationship to each other and in relation to the view port, and of course, horizontal scaling should never become necessary.
In retrospect, text only zooming appears more like a workaround from times, when only few people would understand what responsive design is.

Right…

Somewhere between 500% and 1000% there probably is a case for horizontal
scaling. And good responsive design needs to do more beyond 300% or so.

In memory, that's exactly what happened.

Responsive design that doesn't consider text-only zoom seems to be a bit
broken still.
Is text-only zoom really dead? I might be on a limb, but I'm not inclined
to write it off.

Traditionally I did not want images to zoom with the text, and I was
a Firefox diehard until 3.6 for this reason among others. Trying to
read sharp clear text with something big and blurry next to it
made reading difficult. Now, if it's a problem, I turn off images
instead.

Definitely, and at last!

I'm not entirely clear what you mean here. It is very hard to do both, as
only RWD really gives you options for changing the layout when expanding.
With text-sizing it meant having buffers around text, but you need media
queries (or some very funky floats) to change the interface without RWD.
The only good examples I know of RWD sites that also handle text-sizing are
ones where it is made equivalent. For example (and from a quick look),
theguardian.com sizes everything in EMs, so zoom and text-sizing are the
same.
Does that help? In that case there is effectively no text-only sizing, as
images and layout also scale with text size.

The only reason (use-case) I've heard to use text-sizing in the context of
responsive design is _mallory's, where large blurry images are difficult to
deal with. Are there others?
To me, the solution for large blurry images would be to keep them sharp.
The picture element [1] seems to have good support now [2], perhaps we can
push for zoomed image to use the higher resolution versions?

Another case to consider is some responsive implementations assume the user is on a mobile and hide, or layer functionality behind menus and focus on mobile tasks, etc. When in fact the low vision user may be accessing the site from a desktop and may not be on a touch screen, etc. I could also envision benefits to text resize for main body content but perhaps not other elements -- much like some browser's reader mode. Making assumptions based on the viewport width while not to specific to RWD could be an issue that people associate with the practice.
