It is a somewhat ill-chosen term for the plugins which are allowed /
expected to "scribble" on the newly-fabricated PropertiedUser:  that set
includes the properties plugins, the group plugins, and the role plugins.

The name conveys a slightly off-kilter connotation, becuase it clashes
with the GoF Decorator pattern:  in this case, the plugins decorate the
user object, rather than wrapping around another component, providing
the same interface but extending it (which is the pattern's intent).
