I like using ruff with preview rules, locally - so I have added preview = true to my pyproject.toml, and it seems to be picked up by VS Code, pre-commit, and manual command-line invocations of ruff. However, I think I would prefer new preview rules to break CI. I could pin the ruff version, but would like to avoid that ideally. Could the --preview command-line flag be made switchable, e.g., to allow ruff --preview=false on CI?
