I went back and read parts of the discussions with Ollie, and the
.force=1 thing just magically appeared one day when we were sending
work-in-progress patches back and forth without mention of where it came
from :-/

And I certainly can't remember now..

Looking at it now, I have the same reaction as both you and Kees had, it
seems entirely superflous. So I'm all for trying to remove it.
