 Thank you for your prompt response.
 Replying to [comment:4 pramsey]:
 > This is definitely not a bug, it's desired behaviour. As mdavis notes,
 having a second ST_3DRemoteRepeatedPoints() that used the Z in the
 calculation would match our pattern of "which functions ignore Z and which
 take it into account".
