The logical analogue to the successful crossing:markings=* proposal 
would be a proposal for a crossing:signals=* key that introduces options 
beyond what mappers can already express (in a Babelesque manner) using 
the various crossing=* tags -- without impinging on the entrenched 
interests behind crossing=zebra/uncontrolled/marked.

I'm working on such a proposal, in part to close a gap that mappers in 
my region experience acutely. [1] Unfortunately, I didn't manage to 
complete it before this more aggressive proposal went to an RfC. I just 
hope this proposed deprecation doesn't poison the well for 
crossing:signals=* once it's ready. The original 2019 proposal for 
crossing:signals=* made the same mistake of touching the sensitive 
crossing=* key.

> Also what is the meaning of crossing=no?

crossing=no is for where the road geometry etc. would suggest a 
pedestrian crossing but there isn't one. Some jurisdictions have 
standard signs for this situation. It's probably more common in regions 
where there are laws against jaywalking. If we're really serious about 
deprecating crossing=*, then a more systematized tag could be 
not:highway=crossing, now that the not:* prefix is fairly well-established.
