I know, and it's a pain. If software could easily sort it, fine but it
can't. That's why things that break sorting should be avoided.

Not if there is too much data and no way to know what to choose, or no data

I mean, the rendering can be critical for the use case, but the order and
consistency of the ways is usually not critical for useful rendering. If it
is in your case, you would have problems with lots of routes, because
almost all routes I see are damaged in a few places. If I repair it and
come back two weeks later, same thing.
