I've been thinking about this. Explicit extensions may simplify the client part though and slightly improve performance for the expected use cases.

If you don't mind, I'd continue with the current version as the first attempt, to be able to verify this approach in Khronos Translator, Intel XPU backend for the Triton compiler and SYCL offloading. We can re-visit this API call later in case if integration would show that this is needed or recommended.
