The reason we switched to submodules wasn't to make bisecting easier: It was so that we can make temporary local changes to 3rd party libraries (when changes to GHC or our libraries require them), and then jump back to an official upstream commit without upstream needing to merge our changes.

Ah yes, thanks for pointing that out. So we must use submodules for libraries with a separate upstream unless we can find another solution to this problem. Cheers, Simon
