Thanks for offering to be a "point of contact for upstream developers
to reach Ubuntu developers."
I'm an upstream developer for the Sugar desktop.
Sugar isn't in Focal at the moment, due to Python 3 transition and
Debian packages not ready.
If any Ubuntu developers would like to fix that, I've a reprepro package
repository with enough to get Sugar working well on Focal;
Hope that can help!
