We want to have closed source projects but open access to issues and packages, so our customers can access support and packaged software but cannot see source code. Similarly, we would like to hide from customers our time estimations for the tickets and work time records but maybe expose to the our costs estimation for each task/issue.

It would be also very useful to expose a single file content from the repository, like README.md so we can provide some basic documentation or information. But this could be achieved in many other ways. Maybe we could just add to project features something like "description page" instead.
