i'd rather he implement NIP-42 before NIP-46
one naturally comes before the other
it's my personal crusade to get people to realise this... NIP-65 (for relay devs) NIP-42 (for metadata privacy) and NIP-96 (for media uploads with integration to paid user accounts) and then, ok NIP-46 should probably come next after that, and someone has a clear opportunity to create a service that gives you a wireguard VPN plus inbound routing to your device for NIP-46
could be complicated with more than one NIP-46 bunker active so there may need to be some specification about how to deal with multiple bunkers, as you really only want to have one active at a time, on the device you are using, and nowhere else
