This is not a user-friendly method, IMNSHO.  Customizing
major-mode-remap-alist requires too much knowledge of Lisp.  How hard
is it to imagine someone who puts wrongly-formatted elements into the
alist, like sub-lists instead of cons cells?

If the user just wants to tell Emacs: I want to use foo-ts-mode
instead of foo-mode for language foo, there must be an easier way,
like flipping some simple switch.

So customizing major-mode-remap-alist is _a_ way to express this kind
of preferences, but IMO we should be able to do better.

In another discussion, I proposed to have simpler user option(s) that
would allow users to express this preference, such that, say,
auto-mode-alist would activate this or that mode given such a
variable.  I hope something like that will be possible in some future
release.
