It was indeed intended to be public, but I was forced to rely on a bunch
of GHC specific modules rather than portable ones in order to break some
cyclic dependencies. If those dependencies could be broken in a different
way, the API would be truly portable again and perhaps then we could make
a library proposal to make it more official. If someone feel like putting
a warning about the library being GHC only in `System.Event.Manager`, go
ahead.
