I think we are mis-communicating.  This thread's Subject is "Turning
on/off tree-sitter modes", so I'm asking: what we will tell users to
to do if they want to turn ON cmake-ts-mode?  Surely, the answer to
that question should be part of the solution which we will agree upon
as result of this discussion, right?

I didn't mean to say anything about the imaginary cmake-mode, I meant
to point out that it doesn't exist in Emacs, so our solution to this
cannot be based solely on major-mode-remap-defaults/alist.
