Comment (by pramsey):

 It seems inconsistent all around, to me. What is the consistent rule
 supposed to be? My guess would have been "preserve the dimensionality of
 the first coordinate)" but this test belies that:
     ('MULTIPOINT (1 1, 2 2 2)', 'MULTIPOINT Z (1 1 0, 2 2 2)'),
 I suppose not changing behaviour is the highest good, I hate to see that
 version switch there when we haven't got consistent behaviour. I guess
 it's too late to be as strict as the PostGIS parser (dimensional mixing ==
