Seems to me the risk of running the engine with the seacock closed is vastly greater than the risk of the clamps undoing themselves and then the hose levering itself off the barbed fitting. I've often had to cut them off when removing old ones, so a hose that can jump off all on its own must be very clever indeed.
Absolutely! Just leave them all open (but operate them once a month or so to keep them mobile). People are quite happy to leave cockpit drains open, so why worry about the others?
