Feather asymmetry is a complicated topic.

I am not sure I agree w/ you there.

Drag reduction, the need to maximize stiffness relative to effective area, and preventing 'circulatory interference' w/ the trailing edge of the feather just in front have always seemed adequate to explain their occurrence.

Taking individual feathers as small wings, it is worth noting that wings are rarely (if ever) designed in such a way that the leading edge is *not* closer to the main rib than the trailing edge.

If they are also handy in wingfolding, then that may explain the "Microraptor situation".
