An axiom could be used to add implicit member variables as well to existing structures, which is a step forward for "intrusive reference counting" or a reference to an implicit "proxy" like C++ Superset does.

The use-cases you've presented are expected to be addressed
by reflection in a principled manner.

This paper might be a good starting point:

Reflection likely won't make it into C++23.
