It’s more an issue that WOS needs to implement the rest of the NIP spec from memory, as opposed to me not supporting them.
I’ve seen some alby processing errors too I’ll have to review Incas they should validate.
At present my zap validation doesn’t support lud16 addresses as well. I wrote support, but it needs to be finished.
Effectively Zap metrics/stats are really experimental and I’m not sure they can ever become complete or largely valuable.
