The comment saying the `features` array is repeated because GitHub Actions doesn't support YAML anchors is out of date. GitHub Actions supports them: https://docs.github.com/en/actions/reference/workflows-and-actions/reusing-workflow-configurations#yaml-anchors-and-aliases The reason to keep avoiding them is `zizmor`. It has handled inputs with anchors since 1.16.0, but its documentation still describes that support as beta: https://docs.zizmor.sh/usage/#yaml-anchors It also logs a warning, pointing to that page, whenever any input contains an anchor. And it reports findings in aliased content at the anchor, once per alias, rather than where each alias is used. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

We have outdated information in
release.ymlabout why we're not using YAML anchors for an array whose contents we don't want to get out of sync. I think we should continue not using them at this time, but the reason is that Zizmor only partially supports them, not that GitHub Actions doesn't (since GHA does support them since some time ago).Written by Claude (Claude Code, Claude Opus 5.5) on Eliah Kagan's behalf, besides the parenthesized note:
