NIP-01 is a little ambiguous around REQ messages. One part of the nip says "(...) a new `REQ` is sent using the same `<subscription_id>`, in which case relay MUST overwrite the previous subscription."

And the other part regarding CLOSED messages gives an example of one being sent when a REQ is received having the same subscription id.

Which one is it? are REQs like replaceable events? #asknostr
