Optimized (that is, aero) for 28s but will easily take wider. If you want "optimized for 30" from an aero point of view, I'm not sure.
I'm on the GPs because they come in a 28-hole drilling, at the expense of some weight.
Caveat: disc only. You won't find rim brake hoops optimized for 28 or 30c though, I don't think.

You know, I this won't be formally optimized for 28-30mm tires, but Light Bicycles do have
one rim brake rim that's 56mm deep, 23mm internal width, and - get this - 30mm wide at the brake track. 28mm tires should be only a bit wider than the brake track.
The question is how well your brakes will work with a rim that's 30mm wide. I think the current generation of Shimano calipers should be able to handle that, but I'm not positive. It's definitely a lot wider than any other rim that I'm aware of.
