Maybe that's because such security mechanism are too young in Linux?

Or maybe that any system-wide RT privileges are considered too dangerous?

In these circumstances, maybe that a JACK specific solution could make sense. It
would only need jackd to run as a privileged user (I don't mean root). Maybe
that this would make its way into major distributions more easily than
system-wide RT privileges.

Although I think that granting system-wide RT privileges with a limited runtime
sounds like the best solution. But maybe that this mechanism isn't considered
mature yet.
