The deprecation comment refers to this: https://tools.ietf.org/html/rfc3986#section-1.1.3 we had been using URNs and URLs the old way.

But in any case the fact that we're having this conversation I had had to dig up some RFC from 2005 reflects the actual reason for not following any specific standard: I perceive them and their specifications to be confusing and full of historical context that has changed over time. Assuming that there are no other benefits to using the URN scheme specifically (maybe there are and I am not aware of them?) I'd rather use a simplified URI and custom schemes.
