Yes, we have an open Trac feature request for exactly this.

Agreed, as discussed in http://www.haskell.org/pipermail/cabal-devel/2007-March/000460.html I've also just added a note from an offline discussion that we should use shorter names than I suggest in the above URL, and make them the primary/only names. Thanks Ian
