Across our test suite, this does seem to provide a pretty significant compilation speed up.

Without transitive includes (this change)

Overall, this seems to provide roughly a 20% improvement in the speed of the CI. It is possible that this would also provide a similar speed up in the compilation of code bases using C++ heavily assuming they include what they use fairly consistently.
