Alright, that's good to know.
I will note that in Midgard, the native hardware ops are to load/store

This new lowering pass implements the OpenGL ES blend pipeline in
shaders, applicable to hardware lacking full-featured blending hardware
(including Midgard/Bifrost and vc4). This pass is run on a fragment
shader, rewriting the store to a blended version, loading in the
framebuffer destination colo
