RX100 & RX1: Microsoft leaves them out of new Codec

dpreview article on Microsoft's new codec

Says there that Microsoft has a new codec for RAW.  It includes 34 more cameras but leaves out the RX100 and RX1.

There are lots of "PowerShots" but no Cyber-Shots in the full list:  http://www.microsoft.com/en-us/download/details.aspx?id=26829

Is it possible that Microsoft doesn't care?
