If I understand things correctly, the Powerflarm/LXNAV solution isn't complete. You will see 1090ES ADS-B traffic (which includes aircraft like most airliners and others with Mode-S transponders and approved GPS sources), but you won't see UAT ADS-B traffic, which includes lots of GA folks.

So I think you still need proximity warnings, even after the mandate, if you intend to rely only on PowerFlarm.

Someone please correct if I'm wrong.

If the concern is with power traffic (and it is), its important that the power traffic see the glider as well as vice versa, so a transponder is necessary in a glider.
