It's essential to my understanding.

I'd like to get a clear answer to whether one could write one piece
of software that implements CURIEs. With URI references, it's
clear that one can. But if CURIEs are a cross-language thing,
where each language specifies how to parse and handle them, then
they're not something one could implement concretely, once and for all.

Right; you can implement the generic URI syntax once and for all,
but as new URI schemes come online, you have to stay tuned to the IANA
registry and add more code.

Is there something else I should be looking at?
