Ah, a piece of logic I didn't think of.  Hmpf.

I need to reread all the long comments in automake.in, to also take the
info-in-srcdir-or-not complication into account.

I want to be able to say "no, I do not want this info file to be built
nor installed" for the user.  This is what (at least some) users need.

Also, some users need to be able to generate .texi files.  I'm not sure
if it is always sufficient to let the maintainer generate them (and ship
them plus their .info files).

I don't understand what you mean with "blocked" nor with "access to
`texinfo'".

Thanks,
