That's then required in all clang7, clang11, clang13 and clang15? In the SP2 codestream we also seem to have llvm9 and I can't see llvm13 so that's possibly only via the OBS sle-backports repository? I'll note I had issues with the Factory python3-clang conflicts/provides switching from %python3_sitearch to something else so I reverted that (but only for llvm17).
