I am pretty sure that you have to look hard to find a terminal emulator these
days that does not support color.

I am much more interested in providing good user experience for most people,
and a way to configure things correctly for all others, than providing a bad
experience for all.

Well, I disagree. And given that this so far didn't come up precisely
frequently I am pretty sure that this all is an exotic issue.

Well, TERM is the unix way to tell programs what your terminal can do and
cannot do. you can set it in your .bashrc or similar, there's really no need to
set it invidually for each invocation...

Oh god. With an opt-out switch systemctl is actually very much in line which
behaviour of the popular desktops like GNOME or KDE: they use colors by
default, and if you don't want this, you can enable high contrast themes and
they are. 

Again, I am open to making this opt-out by checking $TERM. But the default
really should be color-ful.
