Putting .di files in the include directory makes sense when compared to C++,
but it's definitely true that they're used quite rarely. They gain you very
little and cost you a lot (e.g. no CTFE). But unless someone were looking to
put both .di and .d files for the same module on the same system, it
wouldn't really be an issue to put them both in the include directory. I
would expect open source librares to use .di files very rarely though.
