Not quite.

I propose to *define* blacklisting as such. 

package-X.Y.Z.W is blacklisted if there exists package-X.Y.Z.V where V > W (maybe I'm off by one position in the  version number scheme here, but you get the idea)

This rule is correct for packages following the Package Versioning Policy. Currently cabal-install and Cabal make no assumptions about the employed versioning scheme.
