And I guess I would call it a "basic usability tenet" that the computer does what I tell it to. Documents, Music, and Videos folders violate this, because if I do the seemingly-obvious thing of just deleting them, the applications that want to use them will just recreate them unless I edit ~/.config/user-dirs.dirs. So, if developers really think they need to 'help' their 'average users' by creating these folders by default, they should finish the job and honor my desire to not use them, which I've expressed by deleting the damn things.

Also, if I want to rename them, the system should honor that. E.g. if I rename "Music" to "music", applications should not then go and re-create a "Music" folder.

Or, you know, they could just simplify my life and theirs by not creating these 'special' folders in the first place.
