what if... (and you probably know what I'm going to say...)
we publish these features on nostr.
Say for example I add "pin-note" support to Highlighter
I publish a new event kind tagging my NIP-89 entry of Highlighter. Thus I signal that Highlighter supports that feature.
That way, say for example I later add "mute-list" support; I could just publish the event.
There is NO WAY someone, not even elsat , will be able to keep up with all the clients and all the features we are all constantly pushing.
But we can push it to the edges, me as a developer, it is basically no extra work to publish an event indicating the new feature when I cut a new version.
