I don’t. But on the other hand the Android mobile I purchased just over 5 years ago supports OpenGL ES 3.0.
I don’t know anything about why WebGL apparently needs to be blacklisted on a large chunk of integrated GPUs. I do know that Intel has been regularly making successful OpenGL and Vulkan CTS (Conformance Test) submissions for several years now. I also know that on the laptop I purchased 3 years ago with Intel HD 5000 graphics I could use OpenGL 4.3 out of the box in Windows and both it and Vulkan in Linux without issues. Since the days of the GMA950(?) the quality of Intel's drivers has greatly increased. I think “continues to do so” (sell "garbage hardware”) is not a true reflection of the current state.
My only complaint about Intel is that their Windows team refuses to support Vulkan on quite a few devices that are clearly capable of it, c/f the HD 5000.
