My mistake, was typing on my phone, meant 10.14.4 (Mojave Radeon VII support) and 10.15 for next macOS version
Removal of OpenCL and OpenGL is not speculation in 10.15. If you watch the WWDC 2018 Keynotes, they specifically talk about moving to Metal only for macOS and OpenCL and OpenGL are depreciated.
So any applications like ones from Adobe (Premiere etc) or Black Magic (Davinci Resolve) will need to move to Metal only in the next macOS version. Premiere already supports Metal, but it has worse performance than OpenCL. CUDA is still king in this area. Something like Davinci Resolve will easily get Metal support, if they haven't already.
If they remove these, all these benchmarking tools and games that support OpenGL in macOS will cease to function and so will applications dependent on OpenCL, they need to move to Metal.
