Unnecessary complexity
So the faffing about with an extra rover (now two helicopters) would have been unnecessary if Perseverance just had a damn rack for the filled samples.
There would then be no need to go back and fetch them. It could just trundle up to the sample return lander and hand them off.
Damn it, do I have to plan ALL the Mars missions?? Don't make me come out there!
Seriously, though... why??
