Not a silly question, but one that isn't necessarily immediately obvious.
Firstly, because the doors are in different places. That brings all sorts of problems - because where do you put the PEDs, and how do you get them to open in a way that doesn't interfere with boarding? /1

Secondly, because your carriages will be designed differently and because some of them will be designed for use WITH PEDs and others not.
Is the gap between door and platform too wide? Can you retrofit the sensors necessary to line doors up?

Thirdly, passengers move through trains and platforms differently on busy stations with PEDs. Pop down the Canary Wharf Jubbly platforms to see this in action.
People queue!
But how do you handle/help them navigate when it's not obvious which PEDs will open or not?

Basically, it's another thing where it seems simple on the surface, but gets VERY complex, very fast.
None of those problems are necessarily unsolvable, but all those solutions cost you either money, access or capacity.
And then the questions again becomes: is it worth it?
