The rating drop was mainly due to general slowdown and time losses.
But even disregarding effects on speed, it's still true that the
experimental connection code is not ready for prime time. It improves
some aspects of the engine but also introduces a couple of serious new
problems that need to be fixed.

I would say it doesn't. Mixing up levels with experimental options
looks like a rather bad idea to me.
