Several of those dwell components can be done in parallel.

You don’t need a warning for opening the doors. The warning for closing the doors will overlap with people boarding.

That being said 10s is too low as a default but it can easily be changed to a more reasonable 30s or more.

There are door opening warning in the Philadelphia subways and metros (PATCO) as well. It makes sense if the train is crowded and a rider is smushed up against the opening door.
