FTR, Mailman considers mm_cfg.py off-limits w.r.t. upgrades -- it will
never touch them.  However it's within Mailman's rights to overwrite
Defaults.py on installs and upgrades.  That's why you should never
make changes to Defaults.py, and always make them to mm_cfg.py

As was pointed out though, if you're making changes to list defaults,
the changes won't affect already created lists.  You'll need to change
those via the web (for most list config variables) or through the
command line bin/withlist for a couple of exceptions.
