Doesn't SDO require the guard and driver to be able to get out onto the
platform, so having the front car off the platform may not be an
acceptable solution even if the signal could be moved.

I was under the impression that they were planning to get rid of guards
on the NLL. Although that wouldn't help the driver, might certaintly
help.

I'm guessing rules on LU are different, as there's a station on the
Northern Line IIRC where the front set of doors are not opened.

I think the key thing is that new operations have to conform to current
rules. I think the end door stuff on the Northern line goes back quite a
while. Is the cab beyond the platform end, or is their one of those narrow
walkways for the driver, beyond the public area of the platform?

IIRC this is Leicester Square or Charing Cross.
"On arrival at the next station, the first set of doors in the first
carriage will not open. Passengers in the First carriage should move to the
rear of the train in order to leave" (or something like that!).
This operates in both directions and I think the platforms are simply too
narrow at that point, there being some structure on the platform.
As these are the doors closest to the drivers cab it isn't too hard for them
to look out and check. Not only that but the actual required stopping point
is clearly marked on the tunnel wall.
