Making it opencl-only would force some of the openmp runtime to be written in opencl, which is not presently the case. Currently that library is written in a dialect of hip, but there's a plan to implement it in openmp instead.

I'd much rather this builtin work from any language, instead of tying it to opencl, as that means one can use it from openmp target regions.
