It's a bool flag that says if by default the library should be registered with the compiler as exposed/unhidden (for compilers which have such a concept, ie ghc). You might want to do this for packages which would otherwise pollute the module namespace or clash with other common packages. It should be very rarely used. The only current examples we know of are the ghc api package and the dph packages.
