This is definitely something I have referenced in my career, that almost all disruptive or behavioral issues are always developmentally appropriate for children. I do wonder if there is a specific line on when it may pass into inappropriate and how to handle that in the best way. My co-workers and I never take anything personally and always use our experience and knowledge to understand that children are just children and are being developmentally appropriate for their age, probably 99 percent of the time. It's surprising to me that there is any situation that a child's behavior may be considered developmentally inappropriate as I can't say I have had to experience that first hand.
