Bolt12 is trash, it abuses Lightning with arbitrary data in a Tor-like way, which makes it slow and unreliable because each hop along the way adds latency and failure probability.

The hype is nonsense that was astroturfed by the minor implementations coping with the fact LND is the standard.

Separately, there was hype by privacy larps, but the blinded paths used by Bolt12 are already available in LND.

Nostr based offers are superior to Bolt12 offers, they work on LND, on the web, offer blinded paths, with none of the performance issues of Tor
