Come from different vendors. This mean that those extension wont probably divide OGL capable GPUs into OGL versioned camps, but in vendor camps. (Nvidia GPUs implementing second, AMD first..)
However since those got ARB status now, there MUST be consensus on them among vendors, so we should see big trio to work on inclusion of needed hardware to their gpus.
Also 4.x and 3.x (to lesser extend) are ment to be executed on "unified" hardware base, so new features relay on the hardware that already is there.
So it those extensions require new hw, we may see OpenGL 5 specification in "near" future.
On the side note: at least AMD seam to be unsatisfied with peace MS develop their DX, so maybe, we could see OpenGL 5 first, and the API that pushes for new level of hw features.
A conformance tests is just as valuable as reference implementation, if not more so.
An public test suit and Reference implementation brings much more for the developers.requiring that vendors submit their hardware for full certification in order to boast OpenGL 4.4 compatibility.

AMD is (as usually) slower to adopt newest OpenGL versions (they are still working on full 4.3 support), but I have no doubt that (one fine day) they will not only support OpenGL 4.4, but also ARB_sparse_texture (already having AMD_sparse_texture) and even ARB_bindless_texture, because why should it be ARB approved if only one of the main companys will support it.
About what hardware level is needed for the new extensions/OpenGL 4.4, here are some clues:
A reference implementation only becomes relevant when the specification is ambiguous and the tests doesn't cover the issue, but even reference implementations can have bugs.
But none of them would guaranty that vendors chose to follow any of it any way.
In the past the pre 2.0 Tests are also not Public.
Because there are sometimes folks from AMD, Intel or Nvidia here: are those formal OpenGL conformance tests based on Piglit?
If yes, me thinks Piglit should be allowed a more beautiful/up-to-date Homepage with Conformance test results etc.
