I'm pretty sure the intent is for it to penetrate spells such as missile shield and force dome, but not indirect effects such as creating a wall of earth. There isn't a good way of phrasing that in GURPS, however, and spells in many cases don't say what they are anyway (it's probably the intent that Missile Shield doesn't work but Windstorm does, but there's nothing in the mechanics of either spell to say that).
