How about just giving up this .666-is-experimental nonsense, define .666 assignments as "official" and leave all OID assignments as is?
Something like that. We probably should never have had such a grab-bag "experimental" arc in the first place. A full audit of what uses .666 is still a a necessary step before deciding what else to do though.
In the future, we should simply allocate per-feature arcs, which remain unchanged throughout a feature's evolution from experimental to release. Just like the config schema delegates sub-arcs for every backend and overlay, etc.
We're probably stuck with the current .666 usages. Again, OIDs aren't supposed to change after they've been used in the wild. But someone should still document what the current .666 uses are.
