I think you may be a little confused as to the scope of the change. A
while ago, the xl driver preferred to use the I/O ports. Now it (and
only it) prefers to use mmio. The xe driver hasn't changed much in a
long time, and still only uses I/O ports as best as I can recollect.
The default changed when mux changed the xl driver.
