What we're talking about is Monticello packages. A Monticello is a set
of classes with the same "major" class category, plus a set of
extensions - methods defined by the package in classes that don't belong
to the package. those extensions methods have a method cathegory that
starts with a star (*) and the package name.
Example: if in the latest Squeak release you browse the instance methods
of class Behavior, you'll see a method cathegory named
"*system-support". Those methods are extensions belonging to the System
The problem with things like Etoys is that they're highly coupled with
the rest of the system, and part of the system depend on it. For
example, trying to remove Etoys triggers an emergency evaluator in
Squeak 3.9RC2. As I see it, if we want to remove Etoys (and either let
it rot in absence of a mantainer or turn it into an installable
package), those couplings would become bugs for the other package
