recovery (lower being harder), so the user doesn't bother fretting
about unpinned packages when he has deeper issues, like VCS
dependencies, to deal with. Also keeps error reports in a
deterministic order.

exceptions of this kind

pasted on after the exception is instantiated, because it's not
typically available earlier.
