I would imagine not all subway systems, especially older ones, have rolling stock where the doors are evenly spaced. I could also imagine having to put the doors in exactly the same place every time could hurt the flexibility of subway systems. There's also the issue of whether human train drivers are able to stop the trains in exactly the same place every time. The Copenhagen metro can do this because it is relatively new, have fully automated driverless trains and was built to have this feature from scratch.

I have heard train drivers say that they can easily stop on the centimeter if they want to. Drivers of the Stockholm commuter trains also seem to handle stops well.
