just my two cents:

ad 0: why do hostroutes require metric 1 and via routes metric 2 ?

      --> the queuing logic in process_routes.c takes care that
          hostroutes are installed first and removed last

          IMO there is no need for different metrics.

ad 1: this is really ugly (having inaccurate troubleshooting information
      is worse than having no troubleshooting information).

ad 2: makes sense from a troubleshooting point of view
