• "Create a merge commit" is good on "release/*" or "hotfix/*" into "main"

This looks good!

Reading through the fluent docs got me thinking, couldn't we automate alot of that so there is not so much configuration? Like if I have fluent installed and run the indexer, it should produce each index file automatically etc...Just a thought and outside the scope of this PR but maybe something for the future.
