I agree that CoMaps and similar apps don't have the feature set that signed-out Google Maps users are losing in this move by Google, so it's not totally relevant.

I don't agree with just calling CoMaps a navigation app in the sense of "how do I get to Point B", though. In well-mapped areas it has business information including specifics about the shop/restaurant, opening hours, accessibility, payment methods, etc. It has points of interest that give information about a location's history and culture, as well as ancillary information from Wikipedia/WikiData. It has information about green spaces, vehicles and bicycle parking, waterways, sports clubs and tracks/pistes, toilets and other public services, benches, water points, and a bunch more.
