There would be at least some value in this feature. I've got a customer (running Asterisk) that uses queues heavily for distributing calls to internal helpdesk lines. They don't want to annoy people by obviously placing them into a queue, so they keep callers ringing until an agent picks up, which is just a couple of seconds usually.

No, most carriers have a fairly limited amount of time they will allow a call to stay in ringing state, so this feature has very limited value.
