scons ought to be updated to version 3 (the latest is 3.1.2), and
supports both python 2.7+ and 3.5+


Scons in ports is 3.1.1. This can compile and run with python 2 and 3. But our USES=scons framework does not know how to instruct scons to run with which python version.

See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241463 for a attempt to flavor scons for python 2 and python 3. Maintainer of the port is rather silent. Does not accept nor reject the proposed solution.

lilypond is another story - noone seems to have bitten the bullet and
ported it to Python 3.
But I don't see a problem in keeping Python 2.7 available for some
time in FreeBSD - it just should stop being default one.

I see both mate-menu and mate-applets require python27, but both build fine and seem to be running well when built with py37. It is possible that one or more applets that I don't use do require py27, but I see no reason for
that requirement on mate-menus. The menus seem to be fine.

Inkscape is another. It builds and runs on py37, but I have no confidence that it runs properly. I have not used inkscape in years and I don't really
know how to test it. I am dubious.

math/gnumeric is one I use daily and it explicitly states in the build that 2.x is required and it is not yet compatible with python3+. It appears that
the default is to simply build gnumeric without Python bindings in which
case python2 is not required, but the port makes use of it, so it probably
needs at least some massaging.

The big one is scons. It is required by virtualbox-ose, and that is rather
important.
