@hundreds-father-404 I’ve started using

./pants update-build-files --check

and get these rather verbose info lines:

18:29:02.26 [INFO] No required changes to BUILD files found. However, there may still be deprecations that `update-build-files` doesn't know how to fix. See <https://www.pantsbuild.org/v2.9/docs/upgrade-tips> for upgrade tips.

What do you think about including the “… However, there may still be…” part only when not running in check mode?

Sure! Good idea

Ok 🙂 https://github.com/pantsbuild/pants/pull/13855
