If you read the NPRM for ADS-B, you'll remember that you cannot even get
above 10K MSL without ADS-B regardless of the aircraft, glider, balloon,
lawn chair... makes no matter.

So Transponders now, and ADS-B later.

I see they want to require transponders in all gliders, with the
transponders always on.
