having ~10 (other) macros defined for g++-15 -std=c++22 is yet better than

You're refuting your own argument, because if g++-15 would need 200 positive
macros compared to g++-7's 100, g++-7 would need 100 negative macros.

There is no point in time at which both can do with 10.

The good thing about positive macros is that an old compiler never needs
maintenance. With negative macros you have to keep adding them to it.
