18375	warn on waterway and highway shared node that is not a ford	aceman	team	"Currently JOSM properly warns when a waterway and a highway with the same layer intersect without a shared node. The user is supposed to make a bridge, culvert or a ford. But it is possible to silence this warning by adding a shared node, without any tags. Such a 'fake ford' makes JOSM happy, but introduces invalid data. Waterway and highway aren't normally supposed to meet in the same vertical level. One exception is a ford, but then it needs a ford=yes tag.

I suggest JOSM also issues a warning if that shared node has no tags.
Maybe there are other cases different from ford where the ways meet in a shared node (maybe e.g. a weir) so it is up to you whether any tag is enough to fix the warning, or it must be ford=yes specifically.

Also note the ford=yes can be tagged on the way inside the riverbanks, in which case the shared node will still exist, but not have the ford=yes tag itself. JOSM shold cover this case and not issue the warning either.
