FWIW both AMD's OpenCL runtime ( https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime) and CUDA equivalent/portability layer (https://github.com/ROCm-Developer-Tools/HIP) are open source.
I have no idea of POCL/Radeon compatibility (but would be very interested to find out!), but have had incompatibility issues with my first gen Threadripper + POCL in the past -- I should try again on new LLVM / POCL release. As far as the Radeon VII goes, I use it for a for a development platform for code running on MI-60s and it is a very good compute GPU. Better bandwidth than a Titan-V and similar single/half FLOPs but only ~1/3rd of the double FLOP rate. Not bad at all considering the nominal price difference. The main area where the Radeon currently falls behind is in profilers (nvprof is far superior to rocprof) and other ancillary software (e.g., CUDA-aware MPI or CMake support, some options exist but definitely are not as well developed).
