Well, I think what we call "design" has two parts: one is "theming" concerns and is made up of things like colors, icons and cursor shapes (to give an incomplete list); the other is more functional and has to do with the logical structure of the various inputs and outputs in a UI. Generally speaking, I think the former concern should be totally under the user's control while the latter concern is what UX people and front-end devs should be doing.
