Hello Stojadinovic Stefan,
Welcome to Microsoft Q&A forum.
As of now, I don't see any plan or announcement about reinstate these games on the Xbox Store from Microsoft. This is a public forum, so moderators and admins have no access to the backend tools or service. So in this case, you can submit your feedback directly to the Feedback Hub app built into your Windows computer. The suggestion there will be deliver directly to the engineering team to consider.
However, as I understand, old games and Wolfenstein tend to have issue running on newer computer and operating systems. So even if there are any plan to bring back the game. It is most likely in the form of a remake or remastered version. Thank you for your understanding.
