Same reason they haven't made a super heavyweight division in mens - not enough fighters in it to justify the creation. And the fighters in it can cut enough weight to make the lower division.
And that was when Brock walked around at 300 pounds, and wanted a SHW division. If they wouldn't create a division for Brock (who was the all time biggest PPV draw in UFC history), what's the chances they'd do it for a much, much smaller draw in Cyborg? They made Brock cut 40 pounds to fight as HW, they'll make Cyborg cut an extra ten pounds to make 135. That's just the way it works - if you're in a very shallow weight division, they're not interested.
