So you're saying that it's difficult to preserve the old behavior,
introduce split-window-preferred-function and also make sure that
split-window-preferred-function is only called once?

I guess you're right.  It would require a different organization
(e.g. moving or duplicating the calls to window-splittable-p outside of
split-window-sensibly).  Not worth the trouble.
