I was under impression that somebody did it already once and it fell through
cracks when has been moved (?) to compiler.h.

Ah, now I see it, https://lore.kernel.org/all/YKeghxRY4FeOKuwb@xxxxxxxxxxxxxxxxxx/.
It was asked, but till now never fulfilled (maybe Reported-by:/Closes: tag?).

And explanation before was given here:
