I really didn't make my question clear, my apologies. This is about projects, apps and systems that rely on these codes. Systems developers generally prefer unique identifiers.

This isn't about fighting the system, or being free from oppressive, tired and useless bureaucracy. The question has nothing to do with feelings or preferences. I also prefer BTC, and have gotten used to it over the last 8 years - but who cares.

I suppose the actual answer is: We haven't got to that stage yet. Which is understandable.
