Agreed.  (Or at least, they should be a very last resort.)

Continuing to alt-click (blue-click) actually cycles through the halos
of the various submorph layers that your mouse is over, so it probably
wouldn't work as a way to toggle halos on and off.

You have a point about being able to invoke the world menu without the
halos going away, but mostly I think of halos as a very temporary UI
element... something that you usually use immediately after bringing up.
 So, having them disappear when you attempt to do anything else
significant seems reasonable to me.
