Despite of the name of ClassModifiedClassDefinition, it is announced also
when traits are modified. I don't know if Trait should implement #layout...
but it is not.
I reproduced using this:
Trait named: #DDDD.
Trait
named: #DDDD
uses: {TSortable}
category: 'a'.
I guess that ClassModifiedClassDefinition is not only being announced when
a class changed but also it is being announced when its superclass changed
(in the case, "propagated"). So the purpose of #isPropagation is the check
that. But I'm not sure this announcement should be done for the
subclasses...
