Yes, sure! I am arguing for whatever is necessary to reduce the total compilation cost. Pruning headers, rearranging source code to have fewer trivial modules and to reduce the size of very often included headers, even gasp sometimes using pointers just to reduce compile time! I understand that runtime performance is a very high priority for Blink, but it really doesn't matter sometimes if certain things are heap-allocated. Like things that are very expensive to instantiate anyway and that don't occur often. These will incidentally tend to have "heavy" headers, too.
