I agree that the wiki should be consistent on the use of these two ways
of mapping a highway crossing.
Personally, I always use highway=crossing on nodes and only
footway=crossing when I can connect the point to a pedestrian feature
for routing purposes.

Thank you, Andrew,
According to the "Sidewalk as a separate way" proposal, which was
approved in 2011,
When a highway=crossing node is present on the main road, a way
connecting the sidewalks on the two sides of the road should be
mapped. Not to override the well-established meaning of
highway=crossing, this way should be tagged as follows:
highway=footway
footway=crossing
However, the OSM wiki “tag:highway=crossing” directly contradicts this;
To map a pedestrian crossing, place a node within the way representing
the road, and set this highway=crossing tag on the node…
footway=crossing and cycleway=crossing are sometimes used on ways
which lead from a sidewalk to the crossing node (the node which has
this highway=crossing tag). *This is not the preferred way of tagging.*
Is this a simple case of information not being transferred from the
approved proposal to the wiki?
I have no preference on how a pedestrian crossing is mapped, but I am
keen for the wiki to reflect accurate information. If we are following
the approved proposal "Sidewalk as a separate way”, does anyone have
objection to the wiki being changed to reflect this?
Cheers

Subject: Do we map pedestrian crossings twice?
Apologies if this has already been discussed. I searched the
tagging list, but couldn’t find it.
Users have been adding pedestrian crossing tags on ways in
addition to the street connecting nodes. In effect, a single
pedestrian crossing is tagged twice. To me, this would seem
contrary not only to the OSM wiki page, “Tag:highway=crossing”,
but also contrary to, “One feature, one OSM element”.
Example:
https://www.openstreetmap.org/edit?changeset=86290585#map=20/39.63167/-104.89726
I’ve been told by a user, anecdotally, there’s a Slack group that
decided this is correct. To my knowledge Slack groups do not
supersede the OSM wiki. I assume mapping a crossing twice is
incorrect?
