text: Title: dnspython3 packages, migration path?
  Body: The current dnspython3 package is still [1.12.0 on pypi](https://pypi.python.org/pypi/dnspython3/1.12.0).
  
  I'd like to see new releases there too: Dummy pypi packages which require the new dnspython. So users become aware of the obsolescence.
  
  (For packaging rpm and deb, this is no problem, as it's possible obsolete and provide other packages)
