Ubuntu 20.04 comes with Python 3.8, so we'd loose coverage for all of
Python 3.5, 3.6, and 3.7. In my experience, the jump from 3.6 to 3.7 is
especially worrying because they changed some encoding defaults that
call for trouble on older versions when testing only with Python 3.8 (I
ran into this when I ported LilyPond to Python 3). So I foresee many
reports of broken scripts when we keep the minimum requirement at
Python 3.5 without testing. Or we bump it all the way to 3.8, which
cuts support for many distributions in use...
The same argument applies to most other distributions, including Debian
10 and more short-lived ones like Fedora where the oldest supported
version (Fedora 32) ships with Python 3.8 as well.
