we could implement it but it wouldn't have zaps, as there is no spec for that yet. the only usecase I can see is profile tipping with no-zap? That's not a huge priority for us.
One thing we could do is make a spec for adding a bolt12 to your profile, but we would still need some code that connects to the lightning network and fetches a bolt12 invoice from a bolt12 offer.
This is a nontrivial amount of work for a feature most people won't use, not to mention passing bolt12 invoices for payment wouldn't work for most wallets yet, or even any NWC wallet.
