crossing:markings is just about this, road markings, and while
crossing_ref=zebra wasn’t documented for a long time, people that added it
around here told me it was about the presence of road markings as well.
Crossing=zebra is about a zebra crossing, it implies also vertical signs- in
some jurisdictions and some conditions at least - and it implies that there
aren’t traffic signals.
Neither crossing:markings nor crossing_ref (as it is applied here) say anything
about traffic signals. Here you will usually have zebra markings on signal
controlled crossings, but they aren’t zebra crossings of course, still
crossing:markings=zebra applies. And many of them have the crossing_ref=zebra
tag (I ignore this tag, it does not follow any consistent logics here,
definitely not a tag I would want to base navigation decisions on). Maybe they
are when the signals don’t work (not sure about it, the law here requires
vertical signs for zebra crossings, unless at road intersections).
As you may be aware, iD used crossing=zebra for its Crosswalk preset
between 2014 and 2019, during which the vast majority of occurrences
were added. [1] So whatever it may have originally meant has already
been diluted to the point that you're probably better off supplementing
the tag with something more explicit if you care about the additional
nuances you're describing here. In general, crossing_ref=* is supposed
to be a localized, holistic approach to classifying crossings. If
crossing_ref=zebra is itself too diluted, then perhaps you could use a
different value. Unfortunately, it's a Monday, so all I can think of at
the moment is crossing_ref=zebra2. XD
Even if it weren't for iD's long-gone preset, I don't think an
ostensibly global tag should be defined based on the narrow provisions
of a specific country's laws. But as you're only defending
crossing=zebra from deprecation, rather than promoting its usage over
less provincial tags, an alternative to deprecation would be to give up
on crossing=* having any machine-readable meaning on its own and allow
it to be an any-tags-you-like situation, similar to ref=* on ways.
