It can be switched to Python 3 by changing the Build-Dependency to python3-dev and passing PYTHON=python3 to configure. However, that seems to require a soname change (especially because the current one was also used in buster), so what do we do, custom soname until the next time upstream bumps it?

sagenb is not Python3-compatible, and won't be as far as I am concerned.
Just dropping it is fine IMHO.
