The downside of archiving is that the project in question is then not accessible via the dashboard which might not be desirable. ### Proposal Add an option in the "Advanced Settings" under "General Settings" for projects that allows a project to be marked as read-only via the user interface.  ### Links / references https://gitlab.zendesk.com/agent/tickets/85798
