also, yeah, this is part of the problem with the whole client ecosystem altogether... 

nobody seems to know what to do and they do nothing at all, not pointing fingers specifically but the lack of implementation of NIP-42 means the gate to paid relays and chatbots are both quite closed

and most of the relays don't process it properly either! pretty sure you have to write a custom plugin for strfry and the rust relay not heard anything about it supporting this feature, even though it seems to be the most popular
