In general the more you CAN configure, the more you MUST configure. For an app that nothing else build on top of, that's fine. For the OS, all the apps expect it to work a certain way.
I'm annoyed by apps that (for instance) move the window min/max/close button cluster. When the OS does that, how many apps break? And that's a trivial UI piece.
