Currently the Warning / Info Message that you are using Unity Constraints is displayed as a message at the bottom of your Avatars Validations in the SDK.

This results in it easily being overlooked and in general being harder to find.

Turn the Message into a Warning that is displayed at the top of the Validations.

This would result in way better visibility and even people who don't know about this transition to be better informed of it.

It would also make it more consistent with the message that you get when you still have Dynamic Bones present on an Avatar.

The second pictures shows the current message and the first one shows how this kind of message was done for Phys Bones:
