Jarvan's Cataclysm, Anivia's Crystallize, and I think Trundle's pillar all use code similar to those of minions. Back when Sejuani's Q shoved minions aside instead of knocking them up, someone made a video of Sejuani breaking through Anivia + J4's walls with Arctic Assault.

So yeah, the walls sometimes fall privy to unit collision ignorance.
