yes, specifically for note zaps. It must be clear its zapping to a profile instead of a note. If they don’t they will be at risk of getting pulled randomly like damus. Not sure why podcasting 2.0 apps are allowed since this is the same as note/content zapping.

If the goal is to "zap", maybe. If the goal is to send sats for a note, thats already possible using any Nostr client: View quoted note →

Rename to "tip (formerly known as zap)" in the interface and keep everything?
