Block performance data in VNXe3200/3150/3300

The SMI-S guide for vnxe3200 does not indicate block performance profile as being supported. Is there a plan to provide this information through SMI-S just like the VNX and VNX2 series. If not, is there any other interface that provides this information?

Similarly for vnxe3150/3300; this does not have an smis interface. The unisphere cli interface also does not have any commands that provide the performance information on luns or others. Is there any other way we can get this information? VNX XML API for File provided the file side information in VNX/VNX2 series. Is this supported in VNXe series?
