When using stack you simply refer to a snapshot by name, it essentially contains the same information as this cabal.config (while adding a lot of extra information) and is downloaded only once and stored somewhere in ~/.stack. AFAIK cabal-install doesn't allow you to refer to snapshots like this (maybe you can refer to a URL somehow?), I think you need the actual contents in a local cabal.config.
All packages in a stackage snapshot must be available on hackage which is why you can use it for cabal-install as well. So for cabal-install there is no dependency towards stack/stackage infrastructure once you've gotten this file, as it has no support for it.
