I think it is important for people to understand the "system". The
analog audio "system" has been standardized for a long time. So,
perhaps, if it is a microphone jack, it should be called a microphone
jack. If it is a line-in jack, it should be called a "line-in" jack.

The two have different "levels" (volts/amps/
watts/power/amplitude/bias/whatever), and a different impedance. So
they should be kept separate, as much as possible.

And it helps when users of the equipment and software know the
difference. There may not be an "ideal" situation, but everyone should
know what the situation is.
