yeah, that's why I didn't go with "NIP", because some nips are quite broad, e.g. if you say you support nip-51, what does that mean? *all* the kinds nip-51 defines?
instead a simple "mute list" feature flag would be more precise
the main problem with this idea would be standardizing around names, e.g. "mute list" vs "mute-list", but we can easily normalize this like we did for the wiki nip.
and ultimately developers can take a very simple quick look to see how other developers spelled "mute list"
