Just don't call it a feeder, it is a "single branch circuit" and put the breaker on the line end, in the house. Then you get the exceptions.
You still need a disconnect but that can be a 2 pole snap switch or two single poles marked "disconnect". The switches have to be rated at the load and 15a or greater.
Personally I would use a 2 pole 30a to make everyone happy.
