I had proposed such a change a while back, not too long before the thread
in question, along with a request for people to reply to the list or to me
directly if they used C-z suspend-frame in GUI emacs. FWIW, I got no reply
saying that they did use the binding, and multiple people saying that they
had rebound C-z themselves (which I have been doing for 25+ years).

What I would characterize as the major objection was the desire to have
emacs on a tty respond reasonably to at least one of the canonical ways to
end a tty program, C-c or C-z, along with reluctance to strongly segregate
the keybindings between tty and GUI, at least as far as commonly-used
functions were concerned.

I think that there is a reasonable technical solution available here where
hitting C-z and then nothing else for a few seconds provides enough
guidance to the user, roughly along the same lines as what the very popular
package which-key already does.

(For anyone not familiar, it creates, after a short delay, a list of
possible completions for a current partial command. More details can be had
from:
https://elpa.gnu.org/packages/which-key.html )

There had been talk in the past year about perhaps including/enabling
something which-key or something similar as part of the "modernization"
effort, so I didn't push the conversation past that point.

Hope that helps,
