There is nothing in this which should be particular to side sticks.
The problem involves high altitude take off and would apply to any aircraft irrespective of control system.
A slower acceleration - longer takeoff roll, would require some compensation in rotation rate and / or limiting pitch attitude. If crews overcompensate - too slower rate, or don’t achieve the required takeoff attitude, where the maximum might not be usually seen in other operations, then the ground roll could be more than expected.
The factors reported were the need for faster and higher initial stick inputs and over awareness of the risk of tail strike.
Training refreshed, manuals updated, closing the loop on inservice monitoring; safety management lessons.
