One data point. From the Arch Linux Wiki (https://wiki.archlinux.org/title/GNU):

While most GNU software also provides man pages, the Info documents tend to be more comprehensive. To view an Info document, simply enter:
$ info page_name
Admittedly, Arch Linux is a niche Linux distribution.

Actually, I believe most people read the HTML version of the Texinfo
documentation.

I think Emacs users use Emacs (of course), and the rest read the
manuals in their HTML format.  I have yet to see a number of people
who use the stand-alone reader that cannot be counted on the fingers
of a single hand.  (And don't misunderstand me: I think the
stand-alone Info reader is great, and personally invested quite a few
efforts in developing and porting it.  My Windows port of Texinfo,
routinely available from the ezwinports site, is one of a couple,
perhaps even the only one, which includes a fully functional Windows
port of the stand-alone Info reader.)

Anyway, the initiative for moving info.info to Emacs was from the
Texinfo developers (I'm sure you can find the relevant discussions in
the archives).  So if you think it should be moved back, feel free to
take it up with them.
