Comment(by strk):

 So as of r13250 I fixed the confusion by padding the Z values in the GIDX
 for 3dm geometries.
 The storage did not change as we have a flag there expressing semantic.
 I think the index size grew for 3dm geometries but I could not find a way
 to test it as pg_total_relation_size against an index on 3dm geometries
 gives me always the same value, with or without padding.

 We have to decide whether to backport this in 2.1 and 2.0
