There is another:

To standardize an Advice Id you don't need to change the core XACML
standard. To standardize a new status code you need to change the
standard.

Since your approach necessitates a change in core standard, backwards
compatibility is gone either way, so I don't see a big drawback with
using v3 specific stuff (and not changing the core v3 standard).
