Weapon anims and item anims including IK can be registered.
Allow registering emote animations similar way will be another useful feature which can works as workaround since animgraph cannot be modded by multiple mods.
Registration of new emote animations will open new possibilities and playground for artist and can extend game very well without mod conflicts.
I can imagine how this can be helpful for roleplay and pve servers.
Please think about that feature.
Thank you
