  Why not? It makes it trivial to switch to other branches/packages for testing.

  Is there some inherent reason that using "official release tarball" for any package instead of the the appropriate git branch is better? We don't have an official policy on which to use (maybe we should) but my feeling is to use the git repository unless for a particular package there is a reason not too.

   Personally I'd like to see the idea of "official release tarballs" get lost in the mists of time and everyone just make tags in their repository for releases. There is the question of built documentation in the tarball but I won't even put docs in the releases, just put them on the web. It is 2019.
