Because there are countries where pedestrian crossings with traffic
signals also have zebra markings and it's not obvious that
crossing=zebra excludes crossings with traffic signals (they are even
called zebra crossings too). Therefore these crossings often get
wrongly tagged crossing=zebra.

Besides, the meaning of crossing=uncontrolled is even less clear.

The absence of a highway=crossing (and a crossing=*) tag on a node
shared by a road and a footway doesn't mean that there is an unmarked
crossing, it could also mean that the footway continues on the
sidewalk or that the pedestrian crossing hasn't been mapped yet.
