As I mentioned in https://github.com/llvm/llvm-project/pull/90079#issuecomment-2077691304, CWG index page that we fetch from is not updated yet. I checked with CWG chair regarding most up-to-date source of CWG issue status, and I'll prepare an update to `make_cxx_dr_status` script to reduce amount of confusions like this one.
