See the proposal:


Used whenever you need a case-insensitive comparison of two strings, 
usually as the key in an associative container. Does the right thing, 
i.e. stores a cached copy of the downcased string for comparisons only, 
while retaining the original string's casing. No current solution in the 
platform. Both the Snap Framework and Yesod have standardized on this 
package as the natural way of representing map keys in web programming, 
which are often case-insensitive (e.g.: http headers). In wide use: at 
the time of this writing has 48 reverse dependencies on Hackage."

Is that reasoning agreeable for you?
