It scares me a bit to have different versions of the same package
putting files in different places (pypi package vs upstream tarball).
But that's probably live-with-able.

But this is a complete non-starter. itstool does rather intricate things
with XML. It's quite a bit more than parse-and-forget. To change it to
use lxml would require a complete rewrite, and I'm not even sure it can
be done. Most XML libraries don't let you shoot yourself in the foot as
easily as libxml2 does.

It's unfortunate the servers don't just have >=2.0.1. It's been out for
a while now. This isn't high on my list right now, and it's too late in
the release cycle to switch anyway. I'll get back to it after Juno.
