Hey I think I found a simple solution to the nip-17/nip-59 spam/deletion problem.
What if we add the ephemeral key we sign the giftwrap with, in the rumor of the message itself.
This way, the receiver can always sign a deletion request, since they now have access to this ephemeral key, no special relay handling required.
Do you see any security concnerns with this approach?
