I agree that these events are broken and has very different semantics from
other before* events. I would be fine with adding non-normative section
describing the current behavior as well (or even mark them as deprecated).
I just feel that it needs to be documented in some spec so that authors
don't accidentally find them on their own and start mis-using them.
