Received, and queued for review — apologies for the silence up to now.

This is a maintainer-side backlog rather than any verdict on your contribution. We
had a large number of open PRs with no reply on them at all, which is our failure to
manage, not a signal about your work. Yours is in the queue and will get a real
review with a real decision.

I'm not going to give you a date I might miss. What I can tell you:

• Reviews run oldest-first.
• If this PR has gone stale against main, say so and I'll prioritise closing it so
  the queue reflects what you actually still want landed.
• If you're submitting this for bounty credit, link the bounty issue in a comment —
  several contributions are eligible and we'd rather pay you than have you wonder.

Thanks for your patience, and for the work.
