Just an idea, i'm entirely not sure if this is possible, please tell me if this is unrealistic.
Some sort of UI when creating an avatar kind of like Unity's humanoid rig assignment to assign certain bones manually so you don't need to rely on the Heuristics all the time (though you should name the bones right.). This could allow for re-initialization of the avatar rig in case you have your finger bones or something named wrong, and you can manually assign and fix it, not having to go back into blender and rename the bones, then re make the entire avatar.
