I mean that it would not change the current binding for C--.

I personally agree with Richard that C-- and C-+ is a better default
and I also think it's okay if negative prefix argument is only on M--.
However, Eli has stated in Bug#28182 that he doesn't want a backward
incompatible change.

AFAICT, s-- and s-+ has some precedence.  It's used in Sublime
Text.  Atom and VSCode use C-- and C-+.  This is from searching the
web.

Familiarity and ease of use.  BTW, we have more than two such keys:

     C-x C-+         text-scale-adjust
     C-x C--         text-scale-adjust
     C-x C-0         text-scale-adjust
     C-x C-=         text-scale-adjust

Best regards,
