With all these different representations of notes and profiles in Nostr clients, should we start again to include mandatory notices like in the days of the browser wars?

Like "This profile is optimized for Primal"?

Do we need Nostr-Client UI Standards?

One thing is certain: it cannot continue to be this chaotic forever. Once a certain number of users is reached, we will also need representation standards. Otherwise, more exotic clients will lead a completely niche existence, and we will experience a quasi-centralization around a few clients that adhere to standards, making the whole network vulnerable as a result. Because the protocol is nothing without the UIs.

Yes, yes, we could then use these clients over Tor and all sorts of tricks and yada yada blah blah and so on... that sounds good in theory. Market practice usually looks different in reality.
