yeah the reason for the redesigned faceplate is exactly so that end users can fit them in future. OR have stated they would be willing to allow CPs to provide integrated vdsl modems in their own routers rather than use the OR modem once OR / CPs agree a standard (i.e. they accept to use similar chipset etc to the current modem).
In the meantime the engineer visit ensures that early adopters get a good service and the fttc doesnt get any needless bad press from EUs with [censored] diy wiring etc..
Give it a couple of years and it will be a self install with an engineer flying around between cabs changing jumpers.
