I can confirm that it works!

Geoclue wasn't working due to NixOS/nixpkgs#321121 (fixed by using https://beacondb.net/). I wasn't getting any error message explicitly saying geoclue had failed about this (with debug logs on) but maybe I should have with this bail? I also think it might be worth mentioning that you need to configure geoclue to allow timewall to connect with the id defined here. E.g. on NixOS I think it's:

    services.geoclue2.appConfig.timewall = {
      isAllowed = true;
      isSystem = false;
    };

Did you use geoclue.preferred = true setting? I think that's the only case were this was silenced. Anyway, I overhauled both logs and errors related to that part. If fallback is successful then error is only debug logged. Otherwise the error message explicitly mentions that location couldn't be retrieved from both sources and includes the GeoClue failure reason.

This is interesting because I actually didn't have to configure this (I'm on NixOS too). Still, I added this to the README, I guess this might depend on the environment.
