Strictly speaking, Mavericks (and Mountain Lion and Lion before it) were already some way through abandoning Aqua. Lion dropped the beautiful blue scroll bars that previous OS Xs had, replaced the pill-shaped buttons with rounded rectangles, and somewhat flattened the overall UI as well, though not to the extent that Yosemite did.
But even as a fan of Aqua, I think it's nice that some of these elements got toned down just a bit. Really, you could view most of the design changes from OS X 10.0 onwards as Apple slowly toning down Aqua; the original Cheetah looks kind of gaudy IMO, the interface elements draw too much attention to themselves.
I do miss Snow Leopard's scroll bars though, as I explicitly call out on the website!
