This statement is only correct if there are crossing ways using the
crossing node.
However, in practical terms it happens very often that in a first mapping
of a road the foot and/or bicycle crossings, as they are nicely visible on
aerial imaging, ar mapped, but not the crossing foot- and/or cycle-ways,
mainly because the details are not visible on aerial imagery or the mapper
is not interested, at that stage, in foot/cycling details. And the
distinction, at least in Italy, between foot-only and combined foot-cycle
crossing are well visable on satellite imagery. Also traffic-signals are
often clearly visible because of the stop lines. Hence in that first round
it is easy to map crossings and basic crossing types. The crossing way is
then often added later. To me it comes natural not to remove the existing
tagging on a crossing node when I add a crossing  way later.
