I realize that iD makes an apparent big deal of these crossings and makes adding bridges, culverts, and fords easy and gives you a nice pat on the back for doing it. It makes the same big deal if it is a river or a seasonal stream crossing. However, if it becomes important to how, it is vital that it is correct. That's why there's the equally valid forth option to ignore this issue.

It's an "issue" not an "error". Mapping is an iterative process. We both agree there's a road there? We wouldn't want to leave it off just because we don't know how it crosses the streams? (Streams that aren't always there, I have found on surveys of similar roads.)

I have just produced another "issue" by adding a ford to a "Road 311" south of here even though there is no water crossing shown. If you would like to repair it, I'm sure the map would be greatly improved with the addition of the Black Butte River that road happens to cross.
