Which means that a single break in a single wire disables multiple
aircraft systems. Brilliant.

Versus a break in a wire causing a spark that could result in a fire?

I could never find a justification for those home remote control
systems that used house wiring, and they weren't always reliable,
anyway.

Completely different scenario... With the home remote control systems,
you're still using the larger diameter 110VAC wiring... There are two many
other things on the line for it to handle signals very well... I've tried
them before and I often has lights that wanted to turn on even if there was
no command initiated to tell them to go on... A properly designed system is
no more complex than the wiring to the headlights of your car... You are
basically operating the equivalent to a relay, except that instead of a
lower amperage current going to the switch, the "switch" sends a message to
the light in a particular format to tell it to go on...
