Yes, it's ugly.  That's part of the reason for the weird way we define
`tex-mode` in `tex-mode.el` (and that was preceded by other weird ways
to do it).

I have an idea for how we should solve this in general in Emacs, but in
the mean time a hack like the (or delay-mode-hooks tex-mode--recursing)
I used in `tex--redirect-to-submode` is about as good as I could make
it :-(

That's another option, indeed.
