WebGL 2 does.

(Also, the state of graphics drivers is extremely bad; even if your GPU claims to be capable of OpenGL 3+, it may crash the entire OS when you attempt to use it. Rollout of new GL features in a secure, sandboxed environment is quite tough and takes time.)

Which no browser has currently. Yes I know FF has prototype of it.

And on mobile, I am yet to have WebGL working properly without transforming it into a cook plate, when I don't get a black screen.

Meanwhile they do OpenGL ES 3.x without any issues while keeping a reasonable temperature.

And when WebGL 2.0 finally gets out across all devices, we will be doing Metal, Vulkan and DX12 already.
