With the recently added skeletal input system, controller users now have a much wider estimated splay than before. This wasn't accounted for on many avatars, and fingers can frequently end up looking broken.
A new option to adjust this splay on a per-avatar basis should be added. 0% would be the finger splay prior to the open beta, and 100% would be how the splay is now. Users would be able to finely adjust between these values based on preference.
