Yes - I have been to these places.
I can imagine a QA automation suite that constructs transepts across bodies of water and traverses them, looking for discontinuities. It wouldn’t need to be done for every release. It’s very similar to the problem of color matching tiles of imagery.
The scenery gateway solution had better be cloud-based. As an Xbox user I can’t imagine that I’d be able to install a usable extension that allowed for scenery editing or terraforming, but I could use a cloud app with a browser interface.
