That was mostly driven by Pier, who honestly had not much knowledge 
about Plasma. It never really covered what Plasma did and we also 
extended it a lot since then. Which is really important in such an 
evaluation: be prepared that things change. A protocol need to support 
also future ideas.

Due to experience with X I do not want something like set_skip_switcher 
anymore. I rather prefer having things semantically defined.
