+1. If we're discussing PVP changes, the other one I'd like to propose is:
Don't include upper bounds on base, template-haskell, or other libraries which cannot be upgraded, unless you know with certainty that your package will not compile with those other versions. Motivation:
* The bounds will never help cabal choose a better build plan.
...this assumes (as I mentioned in an earlier post) that GHC is never going to ship again with two versions of base (like in the past with base3/4). For that case, we'd want at least something like `base < 5` as upper bound in place (with the policy that `5.*` will only ever be reached if something really disruptive is done to `base`)
