I was under the impression that with ghc, ffi import declarations like this do not escape the module:

GHC can inline the stub across module (and thus package) boundaries, so the #include can escape.
It's hard to tell what header files need to be used globally and inherited by client packages and which can safely be used privately.
No, it's easy: they're all potentially inherited.
