there are many issues with "uncontrolled", especially if you use it to
intend a zebra crossing (as road markings are a kind of control).
crossing=zebra and traffic_signals are not synonymous.

What strikes me is the raise of "marked", which used to be a niche tag for
crossings that were somehow marked but were not describable with the other
tags, and now it is the leading value for "crossing".

crossing=zebra is about a zebra crossing, which is a typical kind of
pedestrian crossing in many countries (i.e. no traffic lights, zebra
markings, possibly zebra crossing signs, according to jurisdiction).
crossing=marked is about any marked crossing.

the wiki should be updated. It means a zebra crossing, and I do not believe
there is ambiguity in this, in the UK or in Europe.

the "approved" crossing=uncontrolled has bugged many mappers for years, and
I believe the current idea about the tag is that it should be avoided. The
word implies without markings (although a different meaning is defined).
