Not that much; NDK supports NIP-46 very easily. I wrote a “5 minute guide to supporting NIP-46” a few months ago. Certainly is a bit more complex but very very slight, I just need to write more docs about it, but I think unlocking a normie-friendly experience warrants it x1000000 Your talk was very inspiring, @rabble. Thank you.

Having a NIP-05 address opens a lot of doors for single-sign-on, beginner friendly UX, bridges to other systems etc. It works both ways. Systems with a NIP-05 type identifier (e.g. that I'm building into solid-lite) can then also use nostr on top of their current system.

What are examples of non-nostr systems with NIP-05 ID's?
