There are thousands of people on the beta channel testing, so there are too many to badge. It isn't quite like beta testing is a regular, ongoing thing like localizations where a contributed person's work is credited.
I'd like to have a dev/beta team to help test and get apps through the process, but that still hasn't taken hold.
Sometimes, the impossible can become possible, if you're awesome!

Regarding a Dev team: once 12.0 is in the wild, I'd be happy to chat with you (irc/Skype/hangout) about what you envision that team doing.
