[tc][election] Simple question for the TC candidates

Just to clarify - I'm actually in favor of dropping the plain
coinstallability rule.

I wrote this before: we have different ways to ensure separation:
virtual envs and OCI images.
People can and do use them.

I don't think this rule brings any benefits nowadays, very diverse
projects can be used together even if they decide they need different
versions of some internal library - for whatever reason.
What counts are well-defined interfaces - this is the only way to
ensure cofunctionality, other measures are simply workarounds. ;-)

Dropping py2 deserves dropping old mindset. :-)
