That would break basic assumptions of how the hook operates. It is
expected that we abort the transaction when the hook returns an error,
so if we were to run the hook _after_ `HEAD` has been created that
expectation would be broken.

So the only viable solution is to create a stub `HEAD`, but as said I'm
not a 100% sure whether we want to go there or not.
