In fact, the force of self centering is more a problem for small 0402 parts!!!!
The force is so strong, it can 'Tombstone' the piece during reflow. This is partially why 0402 is used rather than the more electrically convenient 0204. It's easier to tombstone on the long edge.

Also, if you don't care about tombstoning but need the better parasitics of a 0204 capacitor or the better heat capacities of a 0204 resistor, try them out!!
