I maintain tuna, a leaf package. Upstream is working on the py2->py3 migration.
I expect it to be ready this cycle.  I was planning to replace the py2 deps with
that upstream release.  I can release a stripped down (headless) version in
python3 and I'll do that if my package is going to be removed, but I'd rather
wait for upstream's py3 release.

Can we set dates for removing packages so maintainers can plan what's happening?
I suspect it wouldn't be hard to build a tree from an apt-rdepends graph to set
up a schedule, guaranteeing all traces of python2 are removed by bullseye and
defining the latest possible removal dates for each package in testing.
