Wait a minute, adding a BR python3-test would mean an additional 9MiB ok, but
currently these files are part of python3-libs which *every packages* get.
In other words, for the packages that require python3-test the amount of data
downloaded doesn't change while for all the packages that do *not* require
python3-test, the amount of data is reduced.
This sounds like a win to me :)
Unfortunately, this is not correct.
python3-test already is large.
We just move a small bit of python3-libs (test.support) and we move it to
python3-test for consistency.
test.support is 396K installed (for Python 3.8).
