Not necessarily.  Properties can also be used to determine whether an 
object adopts any specialized behavior. Or the objects can be added to a 
list for centralized management.  Or the objects can call to a 
centralized routine which implements the actual behavior.

There are many ways to get specialized behavior for objects without 
replicating the code that drives the behavior.

When more than one object has a similar behavior, centralizing that 
behavior in a common script will often pay big dividends over the life 
cycle of a code base.

I think you'll find the documentation of the message path much enhanced 
in v2.7.
