   See #33333 (review) & #33435. BSDs are being tested in nightly repos, but merging code here, just to have it reported as broken after the fact, which then requires more changes to fix, isn’t ideal. Issues should be caught in this repo, before merging.

   This should be trivial to add, but requires a third-party action to be enabled. E.g.

   • https://github.com/cross-platform-actions/action?tab=readme-ov-file#supported-platforms
   • https://github.com/vmactions#hi-there-
   • …

   So the main question here is how comfortable are we in trusting those actions to be enabled and run in this repo.
