Let's not conflate two things. I assume you're talking about stack.yaml as
the .stack file format. This should be a completely separate discussion for
multiple reasons:

* That's about Stack vs cabal-install instead of Stackage vs Hackage
* It's completely necessary to have package-level vs project-level
configuration (even cabal-install has a separate project config format
separate from the .cabal format)

This was discussed in ernest at ICFP in 2014, and the resulting proposal
was GPS Haskell. The idea was that Hackage would add support for curated
package sets. Personally, I didn't think this was necessary, and
cabal-install should have just learnt logic to get information from
stackage.org so that adding the functionality to Hackage wasn't a blocker
for getting curated package sets available to users.

In reality, the curated package set feature never got added to Hackage,
cabal-install never added curated package set support, GPS Haskell was
abandoned, and Stack and LTS Haskell were created instead.

It's a wonderful idea.
