## What changed? Make import formatting a part of the build, and test validity with "ensure-no-changes" target ## Why? So we never discuss import order again (hopefully) ## How did you test it? its a build change, so the build will test it! ## Potential risks As long as build works, the only thing I risk is the ire of coworker who want imports to be different ;) ## Documentation N/A ## Is hotfix candidate? No
