I have to say, Orci and Kurtzman really opened up a can of worms with the whole alternate reality stuff due to ST09.
I'd say Jerome Bixby did that with the Mirror Universe in 1967. The concept was always there; Abrams and his collaborators just took advantage of it.
As I mentioned elsewhere, Roddenberry himself reportedly intended TNG to be a soft reboot, only loosely in continuity with TOS and ignoring or rewriting the parts he wasn't happy with. It was when fans-turned-writers became staff members that they brought in more direct continuity ties to TOS. But if Roddenberry had stayed in charge longer, TNG might have emerged more clearly as a reboot and we would've been used to the idea of multiple Trek realities coexisting for the past three decades.
Frankly, just about anyone could make their own skew off of the Prime/Kelvin/whatever universe, etc.
And what's wrong with that? Lots of franchises have multiple continuities, and many of them use the multiverse concept to reconcile them.
Of course, Paramount Television/CBS Studios' practice since the '90s has been to treat all Trek as a single continuity; the Kelvin films were separate mainly because Paramount Pictures was a separate company at that point and so the movies weren't being made under the same corporate roof anymore. But if they chose to do another reboot or alternate reality at some point, that would hardly be unprecedented or even unusual in today's fictional landscape, and there certainly wouldn't be anything wrong with it.
