With this update, all controllers got finger tracking. Some setups are.... not optimal (Looking at you Vive) There's probably cases where users would prefer to not to overwrite hand animations with finger tracking.
Although this can be done on the avatar side, it would be nice if we didn't need to update all of our avatars. It would also give us the ability to disable finger tracking on public avatars that won't ever add a toggle.
The setting should persist across avatar switches.
