The thing is, The Khronos Group is the graphic cards manufacturer (Intel, Nvidia, AMD, and others).
So I think it's far more easier to come up with quickly implemented functionnalities according to the standard if there are already some people working on it before it is standard, instead of discovering what the next function to implement will be on the next OpenXX release.
OpenCL 2.0 looks like a huge step forward for heterogenous computing. ARM especially could use it with their big.Little chips and cache coherent GPU's. Too bad they seem to be quite slow in supporting OpenCL, and they're only just now adding support for OpenCL 1.2 for their late 2014 chips.
Of course AMD will take advantage of it first, and they have the most advanced CPU/GPU integration out there anyway, but it's too bad they also have quite small market share, and their impact on the market won't be that huge.
