I think there are two problems with the message Plasma gives in that dialogue: 1. No warning about the arbitrary code - a "theme" intuitively looks like something that should contain art, not code. 2. Users develop banner blindness and ignore that message. Well-tested themes need a lot of work many theme creators aren't ready for. They're rare. Maybe rename/redesign that dialogue to give an impression of a collaborative workshop where users are expected to be participants (developers and testers), rather than an application store with finished products in which they are consumers?
