This recent wiki change by Emvee
<https://wiki.openstreetmap.org/wiki/User:Emvee> is in my view not
helpful, or even misleading, as it does discourage a wide-spread
tagging practice (if we like this or not is a different question,
but it's established tagging, and the wiki is supposed to describe
the establsihed methods of tagging)
The change describes what a router does with bicycle=no on a node,
see https://github.com/abrensch/brouter/issues/265
Already discussed elsewhere but having routers ignore bicycle=no in
combination with highway=crossing means that it is more or less
useless as routers are they main data consumers while at the same
time crossing data is far from being complete.
My take is that it is not a wide-spread tagging practice and it does
not add new information as weather it is a pedestrian issue can be
deduced from the connecting ways.
We still have the valid mapping practice, that sideways are mapped
with tags at the highway=<street> with no seperately mapped ways.
Therefor we still have highway=crossing nodes _without_ a crossing way.
Some of these still have no bicycle crossing allowed.
How can/should a mapper map this 'new' information now?
Discussed also elsewhere in this thread, but an option is just to
retrain from adding bicycle=no/dismount as it is problematic for routing
while it does not add value, for these highway=crossing nodes _without_
a crossing way routers will not treat them different if there is
bicycle=no/yes/dismount or whatever
If in a later stage the crossing way is added, that crossing way will
have the correct access rights.
Like written, I do not see a need but maybe, like elsewhere proposed, a
new tag should be used instead.
