Template B: This PR does not modify behaviour or interface

E.g. the PR only touches documentation or tests, does refactorings, etc.

Include the following checklist in your PR:

• Patches conform to the coding conventions.
• Is this a PR that fixes CI? If so, it will need to be backported to older cabal release branches (ask maintainers for directions).

FWIW I feel like there should be more documentation somewhere about why we need to peg an older docutils, especially if there's a security fix needed in the future. This may be a separate issue about what's needed to migrate to a newer version of it.

[ulysses4ever]

I totally agree. Maybe we should just leave your issue about footnotes open and consider this pin an (unfortunate) workaround?

The idea to pin docutils comes from Google AI... It appears luckier than Copilot.

I suspect it's better-trained. But still not very well trained, if it thinks pinning an old version of something is a viable solution instead of a temporary workaround.
