That would be very helpful.

"Less" in terms of numbers.  But remember than anybody who really is
stuck on Python 2 for some reason is 100% stuck.  The argument for
bilingual is no less valid than ever for that system.  Sure, it's
usually possible to run a separate instance, but that would mean that
they can't integrate Postorius or HyperKitty with the rest of their
site.

It seems to me that punishing folks who have a dependency on Python 2
is hardly a strong statement in favor of Python 3, while providing
Python 3 support is the strongest statement in favor of Python 3 that
a project can make.  Since I'm unlikely to do much, if any, of the
work, I have no objection to obsoleting Python 2 support if you think
it's too much work.  But I hope we can bear some ugliness for a while
if that's the main objection to bilingual support.

Regards,
Steve
