As a heavy user of Haskell professionally and personally, I think you are a great person if you write a binding to a C library. Any C library. So long as you do a reasonably thorough job. Covering the entire surface area of the library is fantastic.

The barest of C bindings, too. A minimal wrapper for memory management is a much better binding than one that hides the raw API behind an abstraction that may or may not be suitable for every use.
