I think we can. For example, python2-ldb is only required by ldb and
samba in Rawhide. Same for python2-tevent, python2-tdb, and
python2-talloc -- they all interconnected but there are no requirements
outside of talloc/tdb/ldb/samba for python2 bindings in Rawhide.

I've been busy with FreeIPA 4.7.0 release last few weeks and attempts to
integrate it to Fedora this week, so not much progress on Samba side
aside ensuring we aren't conflicting (I rebase daily). There is a
blocker https://bugzilla.redhat.com/show_bug.cgi?id=1607635 that took a
lot of my time this week (and is a hard nut, unfortunately).

I'm going to look into a merge the rest of the week.
