Update:

 - Graham finished the test rebuilds with 3.9 as the default,
   and the archive on p.d.o is updated.  We don't plan to keep
   that up-to-date. Bug reports for ftbfs are filed.

 - Bug reports are also filed for all failing autopkg tests triggered
   by the python3-defaults upload.

 - Lucas made an archive-wide test rebuild for unstable, adding more
   RC ftbfs issues, mostly for python binary-indep (all) packages.
   These don't have the python3.9 user tag.
