Finally this rather obvious idea got an official status:

Is the official status that it has been approved?

No, I mean that it was written down and officially submitted. Actually Peter Constable writes (http://blog.unicode.org/2024/08/highlights-from-unicode-technical.html)

That proposed solution is problematic: existing stability policies and commitments prevent assigning more PUA code points and also prevent constraining existing PUA for certain uses. At the same time, there was opinion within UTC that the need expressed was reasonable, and there was openness to considering alternative solutions. One potential alternative that gained some interest was to establish a registration process, similar to what is defined in UTS #37 for ideographic variation sequences but intended for use with historic scripts.
