Yes, this is a very weird peculiarity if working in Germany, for German companies.
There's only one thing I might add. If you're working in tech and/or in smaller companies, there's a good chance nobody will ever ask for this, even less than for university degree papers, etc - but in many other fields or if you're planning to join a big corporation, I'd still suggest to get one when you leave.
