Actually I'm not sure myself. It has been a while, but I believe it has to do with how the contact
plane is calculated. Most of the dTerrainY collider code was left untouched, perhaps the original
author (Benoit) can tell us more.
However, everything should work fine as it is, without changes.

I haven't done any thorough tests with rays (I'm not even sure collisions with rays will result in
contacts), you'll have to experiment with it.

dHeightfield proved completely stable for us (sphere, box, capsule, cone), and as it utilizes the
plane collider internally, it should indeed be as stable as regular plane geoms. :)
