I noticed that crossing=zebra tag usage is drastically shrinking while the very generic crossing=marked, which was quite unpopular before (2013-2018 below 6000 uses) now went through the roof and is leading the tagstats with more than 1 million uses. What do you think about it, shouldn't we be encouraging people to use more specific tags like crossing=zebra or crossing=traffic_signals instead?
My understanding is that crossing=zebra is deprecated in favor of crossing=uncontrolled / crossing=traffic_signals. In particular, my understanding is that they are synonymous for (almost¹) all practical purposes. (Also, that crossing=marked is not desired either...)
Please explain how crossing=marked is "very generic" and what value crossing=zebra adds.
Additionally, crossing=zebra is not an approved tag (according to the wiki), and "It is not always clear what the intended meaning is when used outside of the UK". This doesn't seem like a tag we should be encouraging.
(Feel free to disagree with the above, but in that case, the correct solution is to a) seek approval for the tag and b) clarify the documentation.)
(¹ Pedantically, I suppose you could argue that crossing=zebra refers to a specific *form* of marking, i.e. repeated white stripes, while the approved crossing=uncontrolled could include crossings marked only by two parallel white lines. However, I would question the value added by mapping that distinction.)
