Presumably you still have /usr/bin/python3 in addition to
/usr/bin/python as well.  So the one thing i think we're both agreeing
on is that we use nmbug with python 3.

It looks to me like you're asking me to change my operating system to
accomodate your naming preference.  I'm asking that we put the onus on
developers who really insist on using nmbug with python 2.7 maintain
their own local patch against nmbug, rather than other developers either
modifying their local operating system in potentially disastrous ways
(/usr/bin/python as python3 would cause severe breakage for at least one
python2-only tool i rely on daily, sadly) or carrying their own local
patch against nmbug.  Given that you and i both expect most notmuch
developers to run nmbug against python3 anyway, i can't understand the
allergic reaction to the suggestion that the smaller pool of developers
(those devoted to python2-only systems) be the one to carry the local
patch.

Anyway, I had no idea that this request for something that i think we
fundamentally agree on would cause any controversy, especially given the
expected size and technical sophistication of the nmbug userbase.

i'll drop this request now because i don't understand the origin of the
strength of your reaction, and already wish i'd spent the time i've lost
on it on something more productive :( I hope if you change your mind
you'll come back and recommend it here.

demotivatedly yours,
