@hans These are some removals, this might help a tiny bit with D149543. I try to look at the core issue this weekend.

@iana Does removing these header affect your module patches?

It might require some more exports in the module map, that should be more apparent after D153832

Nice, thanks for looking into this!

Out of curiosity, did this actually help with preprocessed code size?

I expect it helps a bit, I'm not convinced this solves the vector issue. I have another patch, but I expect that one not to be enough either. If that doesn't help we can not include <__format/*.h> when using C++ < 23 (basically what Hans already proposed). That will solve it for older language versions. When people start to use C++23 they will either have to bite the bullet or start using modules.
