Ah. So considering what Vincent said, something like this?

   Package: some-opencl-using-package
   Recommends: opencl-icd-all | opencl-icd
   
   Package: opencl-icd-all
   Section: metapackages
   Depends:
    beignet-opencl-icd,
    intel-opencl-icd,
    mesa-opencl-icd,
    pocl-opencl-icd,
   
   Package: opencl-icd-all-non-free
   Section: non-free/metapackages
   Depends:
    opencl-icd-all-free,
    nvidia-legacy-340xx-opencl-icd,
    nvidia-legacy-390xx-opencl-icd,
    nvidia-opencl-icd,
    nvidia-tesla-418-opencl-icd,
    nvidia-tesla-450-opencl-icd,
    nvidia-tesla-460-opencl-icd,
    nvidia-tesla-470-opencl-icd,
    nvidia-tesla-510-opencl-icd,
    nvidia-tesla-opencl-icd,

Since we just opened trixie for development, maybe now is the time
to do this, so that the problems can be found via bug reports?

Unfortunately intel-opencl-icd can't replace beignet-opencl-icd
because the former doesn't support old hardware. At least on my
system, clinfo says only pocl and beignet have supported devices.
