Belden 8471 Wire, not the best option?

I was reviewing the specs for Echo and Paradigm Button Stations, and we all know Belden 8471 is the recommended wire for the Stations.

But then I was wondering, in regards to the ground wire, why does 8471 not have a ground and shielding included in it?

Wouldn't it make sense to order 1 Cable type that doesn't need a Drain Wire run additionally?

Then I started to wonder if that means the Drain Wire isn't really meant to shield or run alongside the signal wire.

SO I guess I'm just confused on what the purpose of the drain wire is, if it's not meant to be part of the shielding for the signal wire, or if there is a reason not to spec a Cable with shielding.
