Nostr client devs, what's the status of zaps?

I noticed that I can't be zapped which is due to my LN node not talking nostr yet but some clients don't even allow tips while others allow tips pretending they were zaps. And then there is note1gmlru8n03uvhvf87zrs5me0an8qpdufs77hg6u8ww3uee7s5nklqf552mm who claims somebody zapped him even without any LN setup which makes me suspect there's clients out there that let you zap all the accounts, potentially custodying the sats until the recipient reclaims them?

Should clients allow tipping if zapping is not possible? I think they should but they should warn the user that the tip will not be shown or attributed.
