You may not have meant to, but you implied that no trim functions would stop, as if the cutout was no longer there.
Deep in the MAX threads there's AFM and circuit diagrams that may confirm that trim can still be blocked by the column cutout, that MCAS bypasses.
One human factor that escaped the MCAS designers is the cockpit confusion and startle factor when an apparent trim movement can't be stopped by the column cutout, behavior that was not documented
