Mini starter solenoid chatter

Swapped out the Chrysler starter for a mini; battery is in the trunk. Using a Ford solenoid in the trunk to cut the power during Run.
Mark from MAD Electrical recommends installing a relay between the Ford solenoid and the starter to eliminate "solenoid chatter"; where the mini-starter solenoid fails to disengage.
Searching this forum I don't see any other members posting about chatter. Is this going to be an issue?
