I don't think anything is really truly foolproof. Every idea has pros and cons, risks and rewards. I would hope that the likelihood of a pipe leak is less than that of a power failure/interruption. So I think a closed loop is less risk than a sump return; but I agree that it's not zero risk.

don't discount the possibility of a bus hitting the tank during a water change.
