yes, it's one meaning currently described as "valid in the UK" 
(crossing=zebra = crossing=uncontrolled + crossing_ref=zebra)

But "iD issue" is "load the aerial imagery, look for a zebra"
select a node, search for crossing, select "crossing(zebra)"
iD add highway=crossing crossing=zebra. upload the changeset.
iD never ask you if you known that no traffic light exist.
so it may be an alias for crossing=uncontrolled
but it may be also mean "crossing=* not requested to the mapper,
only the fact that the ground marking is a zebra
so don't try to find am advence meaning", the crossing type (light
or not) is unknown

It's why a just to move "the ground marking is a zebra" out
the crossing key.
With crossing_ref as currently described on the wiki,
a mapper can fill "the ground marking is a zebra" without
any "try to guesss if it's uncontrolled or not-filled" "meaning".
another 'll see that the crossing=* is not filled and may make
a survey or check a street-level imagery to add the missing info.
