The Vision component in actor.xml doesn't appear to be needed anymore and should be removed completely, refs rP9184.
The other special templates had it removed, with the exception of the rubble template (which is a special special template outside of the special directory).
The other nonspecial templates can be owned and arguably have Vision for that reason (players should be able to see their own entities, gaia buildings can be converted possibly and gaia animals should attack).

If someone finds a reason why these two templates do need Vision, nuke this concern.
