Raspberry Pi installations worlwide are I guess in millions, people
access it remotely through terminal emulators or serial consoles.

Virutal Private Servers, dedicate servers are in millions or billions,
system administrators access it remotely through terminal emulators or
serial consoles.

Those are shell users. Shell users expect Ctrl-Z to work and not
because of Emacs but because of the basics of shell job controls.

When changing a key that would drastically deter compatibility with
known conventions one has to consider millions of applications in
shell.

Ctrl-Z is mentioned as suspending the job in almost every popular
shell on GNU/Linux systems and BSD systems. Number of installations of
those systems in Internet prevails. Administrators access it through
shell.

I have been using C-x 5 numerous times today and every day, last year
and last years. I hope that those user experiences may give you more
insights.
