...es behavior depending on whether the full or forward decl are available (which, then, may be an ODR-violation). Effectively the same reasons why the standard forbids users from forward-declaring std:: names apply to doing so to user-defined names. https://google.github.io/styleguide/cppguide.html#Forward_Declarations lists some of the issues, and a recommendation not to do so. Of course you do have the upside is that it can improve compile time. Which is certainly of value, and perhaps that's a worthwhile trade-off when the implementation and forward-declare are both within a single project and thus...

There are known problems with running IWYU over LLVM/Clang -- Zachary Turner made an attempt a while back to get it up and running.
