actually, they did use it. though they were still too lazy mentioning it on the wiki. I also found much more stuff stated in the wiki as being "useless" or "obsolete" actually being used in magic effects.
The Creation Kit Wiki as it is a

The Effect Archetypes section definitely needs help: http://www.creationkit.com/Magic_Effect#Effect_Archetypes
Just note where you found those effects that it says are not used...
