Right. That is to say, it works fine on all R5 implementations, but not
on all R6 ones. It is a backwards incompatible change. Such changes
can be made, but they require a threshold that was not met, and there's
no point in moaning about it now. If new *evidence* is brought forward,
that's another matter.
