@hareldan According to https://wiki.openstreetmap.org/wiki/Sentinel-2, #Sentinel2 #satelliteImagery can already be used in OSM editors, but not as easily as other sources, as it isn't pre-configured, so users have to configure it themselves.
The main issue for pre-configuring it is probably that WMS/WMTS URLs are personalized and a user sign-up at #SentinelHub is required.
