Yeah, there were some serious problems with the redisign in 2001.

Recently = since 1.8, at least.  So we are observing more than  5 years of
good track.

Well, in a sense, Automake is not a build tool, it's more a
maintainer tool.  In the typical case, it is run interactively by
the maintainer of a package to create the tarball.

Yes, there are many cases where automake is run from the spec file
and these are in danger.  If there were a backward compatibility bug,
these may not rebuild.  But, AFAIK, this is not anything that would
prevent people from using Fedora.

OTOH, people might want to use Fedora for software development.  And
building new versions of software packages might require new features
or rely on Automake bugs being fixed.

IOW, what's Fedora good for after its EOL?  If it is a museum
artifact, then I'm spoiling the game.  If it is to be used in real
life, then update to Automake 1.11 is beneficial for the developers
using it and harmless for the non-developer uses (office, proxy,
etc.)

The Automake maintainer is very careful.  So it would not surprise me
if the amount of incompatibilities would be surprisingly small.

Yeah, that is a very clumsy package.

Consider telling it that 1.12 is going to be a valid replacement for
both of these as well.
