Ed, I agree with you … if the core is leaking, it should be
isolated … it will leak it’s contents but no more.
Most people just want one valve to turn off the in-flow when
heat isn’t needed – that’s what I did on a previous installation.

Same Valve I installed over 15 years ago – works fine with a pull
cable. But, again if you do not have the means for shutting off the
coolant flow in both hoses, a leak in your system will end up dripping into
your cockpit. OR you at least need a check-valve in the out-flow
line to keep coolant from coming back in that way.
OR am I missing something – everyone seems focused on only one
valve?
