I don't know, I didn't check which ones are in Emacs and which aren't.
I have more than 70 grammar libraries on my system, and most of them
don't have versions.  If most of those in Emacs do, that's just sheer
luck which can change any moment, if we add more modes.

That would exclude too many grammars, I'm afraid.  And I don't see a
reason to exclude them, since IME they are all perfectly usable and
useful.

But mentioning the commit SHA is fine by me, as long as we tell users
not to assume that any newer version will not work.
