That won't stop the use of platform doors; it just requires a suitable
design.

Why spend the money on trivia when there are far better uses for it. Retro
fitting platform doors is probably a lot more expensive that designing them
in from the start. Plus a lot of victoria/edwardian tube platforms are quite
narrow and adding platform doors would make things even worse.

The other door alignment problem could be the driver's ability to see
the ATO stopping mark; IIRC there was no view directly to the side of
the driver's seat on 1983TS.

Maybe, but thats hardly beyond the wit of man to solve.

Not if the place where you want to insert your window contains a
necessary structural component which would make it cheaper to build a
new vehicle.

I doubt 1 window would influence structural integretary that much. They're
frame based, not monocoque.
