Hi Ian,

Thanks for putting together the proposal.

If we will now be using git submodules for external libraries, can we
not just use submodules for all libraries? That way the GHC repo hash
will uniquely specify everything needed to reproduce a build. Right now
it is painful to do any sort of bisect operation---doing so requires
digging through build logs to find fingerprint files for past builds.

It looks like the proposal will leave us with the pain of fingerprints
and add the additional pain of git submodules. I am very much in favor
of just using submodules for everything.
