I'm finding it not intuitive and not generic enough, I'm wondering how
that didn't affect Open-MPI, which as IUI uses this convention.

It means that


disables cuda *and* opencl, while intuition would have told me that it
disables cuda but enables opencl.

Also, one would for instance want to be able to do this:


To be able to enable x86 before the default linux, but disable cuda and
opencl, but enable nvml, as well as all the other usual plugins (without
having to know the list, which is important for future extensions).
