+  #     [Spec Constants] Improved handling of invalid/unsupported spec. constants
+  #
+  #     Two main changes to how `Kernel/ProgramSetSpecializationConstants`
+  #     are handled:
+  #     * They may now output either `INVALID_VALUE` or the new
+  #       `INVALID_SPEC_ID` when the provided list is invalid.
+  #     * The OpenCL and level 0 adapters now respond to
+  #       `UR_DEVICE_INFO_KERNEL_SET_SPECIALIZATION_CONSTANTS` with `false`
+  #       rather than erroring out. This fixes some tests that were
+  #       incorrectly not being skipped.
+  #     * `urKernelSetSpecializationConstants` now "implemented" (as a
+  #       function that returns `UNSUPPORTED_FEATURE` for a number of
+  #       adapters.
