Yes. Using the GPU is not that much of a win since for text and 
curve you'd end up sending to the driver large amounts of 
vertices, and the compability headache that the GPU cause are 
endless. OpenGL is deprecated on macOS, so you need a layer on 
top, so you need a shader language... it quickly gets hairy.

A lot of them do, the equivalent with PBR is have one image and 
rotate this, and recompute  shadows and reflections from there ; 
it drastically lowers memory requirements and image decoding time.

It is very specialized and unsuitable for generic UI, where you 
don't have a reference to thr UX of hardware racks.
