There's a big chunk of work getting the python2 dependencies replaced by python3
dependencies.  I think we should track these packages with bug reports, so that
every source package depending on python2 only, and not providing python3 binary
packages has it's own bug report. For now, one big cluster might be packages b-d
on python-sphinx instead of python3-sphinx, another one many openstack packages.

We can only speculate on the amount of work until we have such a list ...
