Do you mean you're implementing a WAI handler on top of http.sys?
That's cool, would you consider releasing it on Hackage?

I think the header key especially would be a bad fit for an ADT: there
are *far* too many standard ones to really include all of them, and
much more than request methods, new ones are made up. Just look at all
the special handling in http-types for the request methods, and
imagine writing those extra lines for *every* supported header.
