Yes a Plan in the system for a 13nm trip is a bit silly but advising someone of your local jolly plans is not a bad idea, and even so, the argument could be said that a local jolly might not warrant that either.
However a suitable airborne enabled, navigation system based, transmitter maybe of the 1090ES type would certainly make it pretty easy to find you. But of course many folk get all upset at the idea of GA having to equip, big brother watching you and all that crap.
Right now is a pretty good case for having such a feature, and a suitable coverage from ASA would help. I think you know what I mean
