I don't understand why they don't just double down on these #include <__fwd/vector.h> etc. headers. They fix everything. The only downside to them is I can't use them on a header that defines a class with std::vector member variables. But if they could make a small tweak to the language so that I could, then I'd take that over the promised modules revolution any day.
