I do not call highway=crossing with bicycle=no|dismount heavily used. On
some locations the density is higher but on quite some places it is not
used at all. Most people understand after some explanation how routers
are interpreting things and see the problem. An educated guess is that
we are talking about 3000 cases that are problematic.

People differ, I like data consistency and try to fix problems reported
and see it as a good way to learn more about openstreetmap.

First observation is that for 95% of the cases the access rights of the
connection ways suffice, so it can be see as pointless tagging. For the
remaining 5% of the cases, things can be fixed by mapping the actual
length of the crossing as separate osm way with the right access rights.
That way the bicycle routes can make an even better estimate on how long
the crossing takes.
