> but what about when the existing codebase is already inconsistent It depends. If it's a self contained code base, automatic refactoring can safely and mechanically update code to be consistent (naming, and in some cases structurally). If it's not self contained and you're shipping libraries, i.e. things depend on your code base, then it's more tricky, but not impossible. "Lean on tooling" is the first thing you should do.
