During current "distance under all circumstances, stay at home", that is likely going to be true (modulo people using multi-AP setups that aren't meshed under one SSID, assuming you use SSID, or who use 2.4 and 5 GHz SSIDs).

Going forward though, I imagine that as restrictions loosen, the usefulness of WiFI connections would drop significantly, as people aren't always at home. It would also not really help in the workplace, assuming a large campus WiFi setup, since everyone would probably be joined to the same network anyway.

The challenge would be privacy - you'd have to send some kind of information (or unique derivative) of the BSSID/SSID, which would introduce some privacy impact too. At that point, assuming you got access to the hashed SSID/BSSIDs, someone like Google with a street view dataset of AP MAC addresses could "enrich" the anonymised dataset with "ordinary location".
