Maybe not the problem described in the text I quoted, but if I have function
FOO autoloaded and (require 'blabla) replaces that with some other
definition, than an immediately following (unload-feature 'blabla) should
restore the autoload, no matter whether the autoload was pointing to
blabla.el or not.

That's a different scenario. We'll cross that bridge when we get there.

As mentioned in another email, if you define with `fset' instead of
`defalias', the modification is not recorded, so the unload won't do any
`fmakunbound'.

Of course.

Can't be much worse than leaving those functions undefined, can it?

It should be adaptable to other emacsen.

My suggestion uses plain `defun' and normal auto-generated autoloads.
It concentrates all the icky bits in one file which does nothing else than
the icky bits of dealing with the conflict between AUCTeX and tex-mode on
the few toplevel functions like `tex-mode', `latex-mode', `texinfo-mode',
and `doctex-mode'.
