Actually I don't appreciate the implementation of anything that strips an immersive aspect of having to be inside the world to look at it. This is especially true of a modification that has no significant opportunity be voluntarily avoided.
If one doesn't want their multiple avatar's presence easily noticed from outworld, they have no choice about that. If this feature violates the TOS, and also strips a layer of immersion from the game, Cyan should notice that it is undesirable by some individuals.
