My smartphones' Adreno 200 does not support it, and if you go by [1]
it's only supported on PowerVR SGX 530/540 GPUs. That info might be
outdated, though. Either way, I think the extension should not be used
for compatibility's sake. VAOs are not supported in OpenGL (non-ES) 2.x
either, and 2.x is still much more widely supported than later versions.
