You are right, of course, it merely follows people, it says nothing of signal paths, and can't distinguish no-signal areas from un-visited areas.
If trilateration signal in a given area is marginal, the data collection should mark the area as marginal. If marginal area surrounds unvisited area, one can be fairly confident that the border is between a visited area and a no-signal area.
For wifi mapping, this is redundant
Not if Mozilla plans to make the data available to the public under terms more permissive than the WiGLE EULA. It could be an example of what Google's Greg Stein called "license pressure".
