Vmca was stall limited so not an issue. Vmcg was achieved to meet the performance requirements specified, albeit with the addition of a gurney flap to the rudder. Of note, neither Vmca, nor Vmcg, have anything to do with the handling qualities of an aircraft. They are purely 'performance' numbers that drive your take-off speeds.
Can't remember the flap bracket failures, and definitely no failure that resulted in degraded handling qualities during a flight.
I'll call bull**** again....
