I don't think having a skill rating in a PvsAI is helping anybody much. The only reason why rating even exists, is so we can create fair matches. But the entire point of PvsAI is that matches don't need to be fair. If i wanted fair matches, i would play PvP.
If i am a PvsAI player, and i want to assess my own skill, i just need to play two or three matches against different difficulty AIs (assuming we have good knowledge of AI rating) and then i know what i can beat, i don't really need anything more finegrained.
So while a PvsAI queue would certainly not hurt anybody, that would be a very low priority feature from my point of view.
