This is good hygiene, and also happens to be required to build Dolphin using Clang modules. (Under this setup, each header file becomes a module, and each #include is automatically translated to a module import. Recursive includes still leak through (by default), but modules are compiled independently, and can't depend on defines or types having previously been set up. The main reason to retrofit it onto Dolphin is compilation performance - no more textual includes whatsoever, rather than putting a few blessed common headers into a PCH. Unfortunately, I found multiple Clang bugs while trying to build Dolphin this way, so it's not ready yet, but I can start with this prerequisite.)
