There's a big difference in function I think we should consider. The a-variant can't take a stud in the centre position, only left or right.
The b-variant can. And also the hollow studs on the top have a bottom. I think it should be made.
And the b-variant, with these "house"-like ridges are becomming more and more common. Look at 39266 and 49311.
And the new jumper, and 1x3 double jumper.
