At least you didn't squirrel that behind a lmgtfy link </smirk>

In any event, it's clear the tree does not seem set up real well to handle
the random removal or deprecation of python2 support.  And considering
python2.7 isn't dead //yet//, I have to question the wisdom of removing
packages that still support 2.7, and also wonder if there's a way to be more
graceful in handling updates to packages whose upstream decides to remove
python2 support.

Or we can just continue down the current Mad Max methodology and leave it to
every developer for themselves.
