Yup, my impression was that there could be a corner case too but I wasn't
sure how much the corner case makes sense, and haven't checked it closelt yet.
I believe elaborating the case might be helpful to judge we should block this
or now. The current approach looks fine in general to me though. I think it's
fine if it's a bit of behaviour change as long as we mention it in the
migration guide cc @cloud-fan too.
