Nip-11 is irrelevant. You shouldn't do anything based on it at this point. Just talk to your relay operator. They will tell you if they support or not.

That's a pretty inefficient system. We're abandoning NIP-11, which automatically reports server compatibility, in favor of manually contacting all your relay operators to ask them which NIPs their server supports? Why is that better?
It's not better. It's your only option today.
Ok, but is there some push to reestablish the accuracy of NIP-11 reporting in relay servers? For the time being, it's not a problem to contact relay operators to ask them what their server supports, but that's not sustainable longterm.
maybe rewrite NIP 11 to say users must contact relay owners by a phone call
Yeah, the NIP-11 query should just return the server operator's home phone number. 🤣
