Feathers extend where the finger used to extend
When looking at this type of picture notice that the feathers in the wing's leading edge exhibit the exact same form as the pterosaur long finger. The feathers extend where the pterosaur finger used to extend.
This would be the exact result when the finger was shortened. The change is not that great, facilitated by "facilitated variation".
