I propose we introduce a clever new concept we can call your "Fizz". You get a first fizz, and a last fizz. You can change it whenever, but you need to have one

I propose we introduce a clever new concept we can call your "Fizz". You get a first fizz, and a last fizz. You can change it whenever, but you need to have one. But a fizz can only be ascii characters without case and no spaces. We just need a way to map (with some but not perfect reliability) your fizz to your identity as proven by some authorative third party.. The point being that 'name' is a term interpreted in culturally varied ways... which when I design most systems I dont care about. so to make it clear, lets not use that any more.
