A new nip should be made, not completely change nip17. Are we out of cool nip numbers or something? Also, I've added support for deleting NIP17 by p-tag to my nip86 endpoint, as requested by @Vitor Pamplona . This helps with bandwidth and spam, and you can also delete by timestamp.. The only reason nip17 seems broken to most is the huge IOS clients did not implement it. Other than that it is has a lot of current usage.. Muddling the nip this late in the game seems unwise.
