I'm aware of that, doesn't mean it's what the rules describe or that
it's necessarily a good idea :-)

I've never heard anyone complain about this, and I suspect that Miklos
found it from code inspection rather than experiencing an issue with it.
So while it can indeed be classified as a bug (and it is), the impact is
not huge.

That said, I don't have a huge issue with shoving this in -stable. I
just don't think it's a big deal.
