Navigation itself still seems to require GSF, but it runs with minimal privileges (w/o network, location etc.). At the moment, the only app with Location, Network and Sensor access is the Maps app itself. Everything else is shut down to minimum. I can load maps, locations and navigate.

Services Framework: installed, no permissions
Play Services: installed, no permissions
Play Store: installed, deactivated

Can anyone confirm what I have written so far?

    SquirrelMaster Play services depends on the Play Store and disabling the Play Store while using it will break a bunch of functionality. You shouldn't do that. It's going to be causing problems regardless of which functionality you use.

      In a profile without Services Framework, Play Services, Play Store:

      Maps 11.111.0202 (1067348547) - map loads
      Maps 11.112.0102 (1067354881) - map is blank*
      Maps 11.114.0104 (1067372434) - map is blank*
      Maps 11.115.0102 beta (1067382438) - map is blank*

      *If upgrading from 11.111.0202 or below without clearing app storage, the map may appear to be cached, but a search for an address will not show the location marker on the map.

      I sent feedback to Google.

        Very honorable having the consideration and foresight to share the exact useful information one would need.
        Thank you sir! Made it easy for me.

            For me, the maps started showing after allowing network access to the GSF.
