We do seem to be in an odd transitionary period as you say. I got basic 3D graphics for my Common Lisp system up and running rather quickly using early OpenGL calls which I was familiar with. I first used GL from SGI in the mid-80's. We are now looking to move to Vulkan across all three desktop platforms, and it's a major undertaking. Installation and dependencies especially are a concern of mine. Our system is open source, and having painless onboarding is important to me.
