This is great. With a bit of extra tool support for this we could actually do without submodules and go back to individual repos. Checking out a GHC revision in the past could consist of querying your ghc-complete repo for the fingerprint and then running the fingerprint tool.
(unless you haven't guessed, I'm not a huge fan of submodules)
What problems do you see with Git submodules specifically? I'm asking because I believe that we might be able address most of the concerns you have by tooling (e.g. by server-side hooks to enforce inter-repo invariants with respect to Git submodules, as well as client-side scripts to automate common developer tasks) so that the perceived pain of submodules can be reduced enough to make the change-function significantly more favorable for switching to Git submodules (+ folding some repos which are very tightly coupled/entangled to GHC into ghc.git itself, such as testsuite or nofib) Cheers, hvr
