Hi both,
Tim - yes this convention would be for issues that are only discovered after release.
As I see it there are two categories of issue we'd want to capture:
1. Do not use: The release has been unpublished (so you need to skip it)
2. Known issues: The release is not entirely broken and works for some users, but contains a showstopper for other users (so either use caution when upgrading, or skip it)
I wouldn't expect it to be used to note minor issues.
As you say there is probably no practical automation for this, although if we were feeling fancy for (1) maybe we could build something that scrapes the unpublished releases list and proposes edits to the release notes of those versions. But while Release Drafter can't do this itself, I was thinking of reserving a section name like "Known Issues" or "Do not use this release" (with corresponding emoji) and putting it in the release-drafter.yml config, to ensure that nothing else uses it.
