Basically, my understanding is that plugging the vac line is helpful at best and harmless at worst. Is that a correct assessment?
The valve operates on vacuum. If the valve is working properly and you disconnect and plug the vacuum line, the valve can't open. The blocking plate simply allows you to remove the valve.

However, if the valve is mechanically stuck open, it doesn't need any vacuum to open and removal of the vacuum line won't accomplish anything. You must remove and clean up the valve so that it is unstuck. Or, you must use the blocking plate.

Plugging the vacuum line is helpful most of the time and harmless if the valve is stuck open.
