AFAIK, modes where C-c C-c does something do not support the concept of

If you meant ielm (elisp-mode has no C-c C-c), then C-; works there and even does something. REPLs can have multiline inputs too.

And, as already mentioned, comment-dwim is not an alternative to
comment-region. They do different things.

You ignore, like, half the things I write. I am out of this discussion.

I do not understand your frustration.

Because, even with the paragraph below, you haven't addressed my response on that subject. And it was a one-line response, FFS.

Anyway, Stefan has written a more expanded message on the same subject.

The heuristics of comment-dwim not always gives the desired results. If
I know that I want to comment or uncomment a region, I prefer a method
that will do precisely that instead of something that tries to guess my
intention and can end doing the opposite thing depending on the presence
of commented-out text somewhere on the region.

I don't see you arguing for adding a comment-region binding in other major modes.
