Right, we didn't want to prevent old code from accessing new
repositories with FS format numbers.

Did we jump the gun adding FS formats? Possibly. It seemed reasonable
to get an early start doing checking at the right layer, but now that it
comes time to actually take advantage of that checking, it's not clear
that getting an early start actually helped us any.

Luckily, we are bumping both FS format versions at once, so it makes
sense to just bump the repos format, while allowing new code to work on
the old repos version and making the new svndiff0-only svnadmin create
option create a repos with the old repos version.
