For a big subsystem that exposes an API, you would be right. But this is a *really* simple problem, all you need is a way to tell it who gets RT privileges, which means uid or gid. So any future solution will be orthogonal to this one, and when users upgrade even a not very smart Perl script will be able to migrate the configuration. How many different ways are there to say "these are the non-root users who have realtime prvileges", anyway?
Unless, of course, the solution that's eventually merged is *really* overcomplicated by comparison, in which case users will (rightly) reject it, and the system will have worked.
