It's a nice and compact solution. However, i don't think the teeth are very durable when the bucket has some weight added to it.. Being that it's only a half bush thickness and held on by a cross axle stud.

Many people think that. But with new parts, it's sturdy enough. (when you dig, the bucket is not ripped off.)
This assembly was made 2015. Maybe today, it's possible to make better.
