Correct me if I'm wrong but creating a new type of bus would mean

that all the drivers living on this bus must be changed to register
themselves on this bus ?

Or does a solution exist to let them live on the platform bus and call
firewalled bus before been probed ?

All the impacted drivers could work on the existing bus with or without
the firewall so I don't want to break
