Currently the physics simulation can go wrong and you can manage to fall through terrain. Previously this was the only approach we could use because there was no way to specify which thing was the terrain in the world.
We could use an environment setting to indicate the terrain, or we could just use a 'terrain' setting in physics. EIther way, the bullet implementation then needs to respect this, making sure that terrain objects force other objects to remain above them.
