Why does this have to be a config option anyway? Shouldn't this be
dynamically determined? How should someone know which to choose?

You just reverted this coding style change, why?
I can't take this patch, sorry. Please sync up and make sure you do not
revert changes that other people have already made to the code, and
resend the remaining patches in this series.
