Indeed.

Indeed, that would be nice.  However, only the committed auctex.el in
the ELPA version has a Version header.  Whenever that changes, a new
ELPA release is triggered.  So the rule would need to regenerate
auctex.el from auctex.el.in but inject the very same Version as the old
one had.

Well, in the end auctex.el is simple enough.  I just have to remember to
bump the emacs version when I merge after we've bumped the emacs version
on master...

I've done it now and merged from master.  Are you fine with pushing
another ELPA release now?

Bye,
Tassilo
