In my opinion mono on win32 systems would use OutputDebugString and on *nix
systems this function would simply send its messages to /dev/null. It should
not send it to console, as ms.net doesn't do that as well; you have to
explicitely set that up in that case.
As there's no debugging device on *nix systems, developers couldn't get
annoyed as they couldn't have any expectations in this case. ;-)

I can understand that, though instead of --diagnostics=trace I would
say --trace=/dev/console or --trace=/dev/stdout
or --trace=/home/me/myfile.log, etc. Same for debugging messages, allow a
user the choice of the file or device to send the output to, instead of only
having the option to have it send to stdout.
