I believe, at the time, the logic was:
 * OpenLayers can't do 3d
 * If we read 3d, when we write it, we will write it wrong
 * It is better to error at read time than fail silently at write time.

I'd be willing to change this behavior, but it was originally
implemented by tschaub, so I'd prefer his buy-in as well.
