Why is this an issue?

  It is possible to use a bare inherited in any method implementation, even if there is
  no base method to call. Although this statement has no behavioral effect, it is misleading and
  indicates a possible programming mistake.


  Since the inherited keyword works regardless of whether the method is marked as
  override, it can also lead to unexpected behavioral change if corresponding ancestor
  methods are added later.

How to fix it
Remove the inherited statement:
procedure TChild.Proc(Foo: TFoo);
begin
  inherited;
  // ...
end;

procedure TChild.Proc(Foo: TFoo);
begin
  // ...
end;
