The super-res is surprisingly usable for making sense of land use changes. With OpenStreetMap editing, one common challenge is that out of the usable (license-wise) imagery, the high-defs ones are old and the new ones from Sentinel are low-def. A lot of switching, squinting, and gusssing is required to understand of what's going on, even when most of the work is as basic as trying to spot this old road in the blurry new image. This super-res seems to do that well enough. It doesn't have enough information to guess the exact shape of buildings and that's okay.

They also do some object recognition, which is useful if you're an electric infrastructure nut. It spotted some solar fields in Shanghai which I've never heard of before -- a look at the same coordinates (30.753, 121.392) on Google sure shows the expected blue.
