History shows that windows-only features tend to rot.

Yes, I know -v -1 will shut up most of the messages, but 1) they are
printed by default, and 2) there's a still an awful lot being spewed

Did you ask them? FFmpeg currently prints:
1. FFmpeg version and copyright. This is impossible to silence.
2. Build date and compiler version. Impossible to silence.
3. configure options used. Impossible to silence.
4. Version of all libs, twice. Impossible to silence.
5. Input/output stream dump.
6. Frame counter.
This usually amounts to 20-30 lines of useless information (most of
the time it's just repeating what's already on the command line). A
one-line error message is easily lost in that jungle.
IMO the default output should be cut down to substantially as most of
that is only useful for debugging problems. We'd obviously insist on
running with -v 1 (or something) for bug reports.
