Three packages still don't sound like something to add to EAPI. Even
with ten, I would have my doubts. Reading the whole thread, lzip
doesn't seem like it's going to live long. Trying to artificially force
it upon people is only going to give opposite results.

Either that, or add it to unpacker.eclass and use it. That's the place
where we handle all the random cruft, and where we can fix it as
problems arise.

I think that'd be a waste of effort, to be honest. I think using lzip
(and lzip only) is the problem, and we shouldn't bury it like this.

If you can't convince them yourself, let our users do that. Gentoo is
pretty specific in the way people handle extra dependencies they find
unnecessary :).
