Absolutely they must be built out of other components. The question is:
who does the building? I'm saying that the plugin designer should be able
to present a complex "plugin" which is actually a ready-connected graph
of simpler components. The alternative is for the plugin designer to present
a "bag of bits" for the user to connect together.
