Going on with a test rebuild of 3.9 as default to file bug reports for more
packages.  The first stage1 packages for 3.9 as default [1] can be found at

  deb [trusted=yes] http://people.debian.org/~doko/tmp/python3.9 ./
  deb [trusted=yes] http://people.debian.org/~ginggs/python3.9-repo ./

The first repo just having the python3-defaults packages from experimental. The
second repo of course will be outdated very soon ...  Bug reports for stage1 are
filed, Graham is now running the test builds for stage2.

The autopkg test results at [2] need checking. There's currently a britney bug
which marks things as bad, and only gets it right after a week. Plus there's no
way to select an "unrelated" package from unstable for a test, and have it
marked as a successful test.  So basically you need to wait until all the 3.9
related fixes migrate to testing for running a successful autopkg test.
