Sorry about that. My explanation wasn't clear enough.
What I meant to say is that most of the paths are not definitive and depend on which satellite image is available at which time.
I just checked and it was probably based on satellite imagery from Bing Maps when I edited it.
(When I'm not sure, I refer to satellite imagery from Esri, Google Maps, Yandex Maps, etc. for verification).
So, like I said, I think a lot of the routes around there are fairly arbitrary and will never be definitive, which means that if you or anyone else has more up-to-date information or is more confident, they can make edits.
It also means that it would be nice to have a way of tagging the properties of paths that are not set in stone, that come and go, and that change shape from time to time.
