ClearCase had elaborate rules to define ownership and permissions. I guess this feature creep was imposed by marketing the product to lawyers and paralegal first. Ever ClearCase install I know of is an awful legacy system superseded in practice by git, even in environments that work on the need-to-know basis. Lawyers and paralegal just ditched version control altogether, surviving on Office365 document sharing and distributed editing.
