OSM has full edit history like wikipedia, so 'undoing the damage' doesn't need to be hard.
They could have a simple flag on edits which say if they're done from satellite data, and if so what age the data is. Any real-world surveys shouldn't be allowed to be overwritten by older satellite data without good reason (eg. spam, or the real world survey was done badly)
