The answer (like so many of the answers for the "complaints" about this platform) is simply "history" and the fear of what might break that you don't know about or actually knowing something will break and having to go through the effort to change something in order to use the feature (often too much trouble for a minor benefit). In this specific case, I have not allowed it on any systems I have managed for the stated reasons above. Had running duplicate jobs been allowed from the start, of course it wouldn't be an issue and I think many if not most shops would use it. The ones that use it as a "cheap method" of getting jobs to run in succession would have just done it a different way.
