How to remove Python3 and dependent ports?

[Chris H]

Well, after a 5 day build session, due to a low resource i386
box. I discovered that I get to start the process all over,
after performing a fresh install. Problem is that Python3
was introduced before Python2 was EOL'd, and removed from
the [ports] tree. Pity Python couldn't be bothered to find
a way to work with both versions. To the point; I received
the following FATAL error, after an extremely long build
session on a meta-port x11/cinnamon:
===>   python3-2_3 depends on file: /usr/local/bin/python2.7 - found
===>   Generating temporary packing list

Hmm... seems to me, by the error, that the actual culprit was
an effort to THWART this exact error. Job well done! :P

So, as it appears to me anyway. I'll need to make a choice;
either I'm all in on Python2, or Python3, there's no in-between.
So I was hoping that someone might suggest a good way, or an
already existing port to remove Python3 and every port that
includes the "REQUIRES python:>=3" line in it. So as to end up
with a successful build.

Thank you for any thoughts, or suggestions.
