A class whose methods are nearly all delegations to one collaborator object — no decisions, no transformations, just passthrough.
Callers talk directly to the real object; trivial passthroughs are deleted.
Before the refactoring
class Manager {reports() { return this.team.members(); }}
After the refactoring
// Expose team directly when the wrapper adds nothing.manager.team.members();
Every consumer pays a hop to reach the real implementation; the middle man adds file count and indirection with no value; future maintenance must update both classes for any change to the delegated API.
Direct access to the delegate exposes its surface to every consumer — only remove the middle man when most of its methods are passthroughs.
Fewer files, shorter call stacks, the implementation's location is obvious.
Deleting a middle man that's actually doing real work — authorization, validation, auditing — that the trivial-looking delegations were quietly enforcing.
