So you're proposing to do away with using NIP-19 in URLs? If that's the case, I'm going to say that I'm not for it.

It normalizes using hex for everything and the real world use cases and counter argument is how many private keys I was given in the early days of Nostr Plebs instead of public keys, because users can't tell the difference.

I'd be fine using NIP-19 in URLs along with your proposed /p/, /e/, etc. Some applications already do this. There is no standard here. I'd be fine with that being the default for MKStack and making it the standard there. Just no hex!
