I don't have the numbers you are looking for but one data-point is that cabal-install itself (which has a reasonable number of dependencies) typically does not compile with a freshly released GHC. This forces to temporarily add head.hackage in CI when a new GHC releases.

IMHO, using head.hackage to test a source-distribution defeats the purposes of testing. We cannot (and should not) assume those building cabal's source distribution(s) are using it, and therefore `cabal install cabal-install` will end up succeeding in our CI and failing for everybody else.

My 2c,
Andrea
