i was thinking NIP-58 badges, but NIP-39 is also a good alternative too, probably even better than badge.

It could be a nip-39 extension, no reason why not, but clients should still handle it like they do 05s

I don't know squat about nip-39, so I can't interject much.

I just read nip-39. I will politely disagree, unless you want to just mash domains and platforms together, which I don't think is technically correct, but begs the question... Why not mash them together, then? #multinips.

Sorry but you're full of crap lol! It's not pointless at all. It may be unnecessary for most people. But not pointless for everyone.
