But that kind of raises issues regarding extensibility, right? How would
you extend a previous version, such that the old one remained intact while
the new one was a superset, without having to have them use two different
prefixes, in a situation where they both might have to coexist?

I haven't thought it out, so maybe its simple, but it seems an obvious
issue for us to thrash on for a couple weeks :-)
