I cannot exactly say I am trilled with this change.  But starting from
the bottom, something is definitely wrong.  AFAICT, the latter 3
packages in your unblock request fail piuparts tests because they cannot
be installed with the following:

"""
  The following packages have unmet dependencies:
   piuparts-depends-dummy : Depends: python-sqlalchemy (< 1.1.0) but
1.1.6+ds1-1 is to be installed
  E: Unable to correct problems, you have held broken packages.
"""

That suggests to me that this unblock request cannot succeed in its
current form.  These 3 openstack packages have other bugs that would be
great to have fixed in testing (a nettools dependency issue), so I would
be glad if that part could get solved.

Thanks,
