That profiler is meant for low-level debugging as its own description says. That is why it does not support DX11 either.

...that Radeon-GPUProfiler is that tool which has only D3D12 and Vulkan support.
Look around for AMD's OpenGL activity more recently, there's not much, which isn't surprising because they've been lagging behind NVIDIA with their GL drivers since forever. I bet they're eager to close that chapter.
NVIDIA seems more committed to GL still, but without having all GPU vendors on board to continue supporting OpenGL, Khronos won't be able to do much to keep it alive.
Please don't make things up. OpenGL 4.6 was released in July 2017. According to Wikipedia, modern AMD and NVIDIA cards both gained driver support for it in April 2018. Intel drivers have support since May 2019.
That is not news, and that has nothing to do with the state of OpenGL.
Please, stop spreading misinformation about OpenGL.
