Let's not backport this to 3.14, as it would break existing builds that have GCC 15 which has musttail but no preserve_none

miss-islington-app · 2025-11-01T16:41:27Z

Thanks @XChaitanyaX for the PR, and @Fidget-Spinner for merging it 🌮🎉.. I'm working now to backport this PR to: 3.14.

Sorry, @XChaitanyaX and @Fidget-Spinner, I could not cleanly backport this to 3.14 due to a conflict.
Please backport using cherry_picker on command line.
