I expect it's pretty much limited to parking brake use only, unlike
traditional e-brakes where it is possible to hold the release and
manually modulate the brake in the unlikely event that both hydraulic
brake circuits fail. Of course sine few people these days know how to do
that it probably doesn't matter.
