"in development soon"? For comparison the Vulkan project began July 2014 and was released 19 months later. That released on multiple GPU vendors and OSes at launch, which Metal did not. So let's say Metal took 2 years from conception to release, even though it only targeted one platform and one GPU (and likely took less time as a result) That means OpenGL was abandoned on OSX roughly 3 years before Metal existed as a project at all. The timelines of Metal vs. OpenGL on OSX just don't line up at all to be any sort of API redirection effort. It just doesn't mesh.
