I think that will depend on the overall story they tell. If the political and social backdrop of the Federation in the overall story they tell is a backdrop that is akin to "ten years before Kirk's TOS", then it belongs ten years before Kirk's TOS....Since it seems that, other than a few references to events and earlier characters and settings and the generic ship designs, DSC is going to bear little resemblance to "ST ten years before Kirk" so why use the ST name at all. Except for marketing and an cynical attempt to sell into an existing fanbase.....
