I'm okay with making "C-c C-q" work in more modes than just C-related ones,
but please do that on master, not on the release branch.

As for M-q, it should be bound to a fill-SOMETHING command, not to a
indent-SOMETHING command.  So from my POV paredit-mode should be fixed to
use some other sequence for paredit-reindent-defun, perhaps even "C-c C-q",
but that is IMO an unrelated issue.

And if you wanted to suggest that an indent-defun command in c-ts-mode be
bound to M-q, then I'm very much against that: M-q already has a useful
command bound to it in CC Mode, and should do something similar in
c-ts-mode; I believe we are discussing that in bug#59763.
