Don't get me wrong, I understand doing the compression ourselves would
yield extra flexibility, but is there a real use case where someone
might want to do one of those?

A tertiary benefit of only using features built into GNU tar, however,
is that it's fewer external dependencies for tla to worry about at
config time.  Consequently, archives are more portable because I don't
have to worry about installing foozip to access someone's archive.
