I don't disagree with your premise.... but it does seem much trickier to
implement. We don't have the nice type sugar in non-types to indicate that
substitution took place. Is it worth adding that for this? Are there other
good reasons to add it?

(Also, this patch seems a strict improvement, and we can add the refined
checking you're mentioning as a second step? I'd like to avoid the false
positives we were seeing with the previous incarnation)
