I think you misunderstood me.

Having a fully working pgp package, means you have full control of the 
pgp stack, you don't rely on hard-to-get out tools, and it can be 
integrated with cabal directly for a full WoT experience.

Also git doesn't solve the hackage problem, there's not necessarily a 
one-to-one mapping between packages and their repositories.
