It's not so much that they didn't want it there; more that they don't care
about that use case at all and it's not something that they want to
maintain or think about.  Similar to the situation with createrepo_c except
that there was less hope that they would eventually take back control :)

The primary reason is just that we wanted it to be possible to run the RPM
plugin on Debian-based distros, and relying on any RPMs would go counter to
that goal.  But there were some other motivations also - at the time, the
Python community was deciding on which technology to use for the new
dependency resolver in Pip, and libsolv was mentioned as a candidate (but
ultimately decided against for various reasons).  One of the reasons was
that nobody had ever made a Python package for libsolv and they weren't
even sure if it was possible - and I found this discussion at the same time
as I was already wanting to package it anyway for Pulp.
