If Sony can make a 28-70 at the equivalent aperture as noted in the subject, why can't we have one for a M43s lens? I mean, the 12-35 is a constant F2.8, but if you compare to the Zeiss offering being the same size as the Panny zoom, I don't see why not......

You would not gain much.  At wider angles, you wouldn't get much better subject isolation, and speed isn't as critical for hand holding.  There's a reason lenses are judged by their aperture at the long end, not short end, and hence why fixed aperture lenses are desirable.  Basically, a 1.8-2.8 wouldn't get you a whole lot more - except size and cost.
