I think it's a matter of design. The Smalltalk integrated environment feels completely right and was designed wonderfully with that intent in mind. The JVM, likewise, has had a consistent and clear scope throughout. Browsers are still not fully scoped out. From year to year, it varies what webapps can do and what the norm is. Furthermore, it was not originally designed with this usecase in mind. All those contribute to it feeling a lot more awkward for this purpose than other, better designed, solutions. Also, JVM/Pharo have significantly smaller scopes which helps.
