Yes, true. However users that don't know about this will also ignore the
key being unlocked as well. Pinentry could easily have a 'details'
section showing more details, such as those.

Not to say that it's not cryptic. The problem that even PID/command is
sometimes not enough to understand for a developer as to why a key is
being unlocked.

But it's a start, and it's arguably something that doesn't come from the
program itself.
