This likely played a big role in the development of the Mini; the connector board failures were the cause of the Blue Lights Of Death and the tractor noise issues that required sending the QC’s back in for repairs. (I would still LOVE to see how many units had replacements) At the same time, footswitch implementation was a frequent target of criticism with people wanting more options for the available switches.
Getting rid of the connector boards and reducing the footswitches got two birds stoned at once.
