Yes, they have. How would you do it otherwise? At some point you need to render all those different tables. Using off-the-shelf comments is probably the most efficient system imaginable.

If you think DB is utterly incompetent you should take some trains in most other countries. I know it's a popular sport to bitch and moan about them (I do it as well) but seriously, the system works surprisingly well. Those displays are also some secondary info screens that were added later and are not part of the core system and thus probably don't receive the same attention as other more important things.
