That's not what you referred to in your earlier post; you advocated a "video only housing instead of building a monster to host the add on flash." I commented that they were unlikely to produce such a housing, to which you replied with a claim that Nauticam made a "video version" of the RX100 housing. The clear implication of the two posts was that Nauticam had made a "video only" housing in the past which they simply have not.
The camera is structurally different. If they had to do a V version for the lx100 it would be good to reduce the bulk by skipping the space for the flash
I also doubt a 24-75mm fixed lens is of any practical use for still images but that's another story
