It is being retired, it is a massive bloat compared to vulkan (mainly because of the glsl compiler), so it is reasonable to say than building upon it is a mistake.
I see know signs that it is being retired on platforms other than mac. With vulkan you have to bloat your own program's code and introduce complexity. Regardless bloat doesn't matter so I don't know why you are focusing on that.
ok chatgpt.
This comment is pretty wrong. Vulkan still uses the GLSL compiler.
