Optional heartbeat message from PT's

Would it make sense to have a specified STATUS message for Tor-style heartbeat messages for PT's?

When running a Tor relay/bridge it's useful to have the Tor heartbeat message to see the activity of your relay/bridge - maybe the same would make sense for PT's too.

Lame anecdotal note: I ran a test bridge for my quic-pt code and just received an email from someone who was using it. I was turning it off because I had an idea that nobody used it.
