I have no experience with SolidWorks, so I'm sure it is as you wrote it. What I wanna say is, that Cura should be oriented the same way as the 3d printer is, and I think this is now the case for most of the printers out there.
But yes, it would be very helpful, if cura automatically rotates the part when you define the CAD it came from. So the plugins from thopiekar should be standard ones in cura in the future.
