I'm not going to losen up these semantics. They might be utterly wrong,
but it's what we have given to users for a long time. If you want to
losen it up send a patch with a good rational for use case that it
really matters, and extended version of the proof below and argue for
it to get included. And take all the blamer later in case something
breaks anyway.
