As I noted before, contexts are fine and dandy, but creating one of
them is a Big Deal [TM]. This means that they will not be used to
devolve authority at fine grain. In fact, given the tarpit method of
creating a new context, and from a language usability perspective,
they arguably _cannot_ be used to devolve authority at fine grain.

Not sure what you mean by that ... perhaps you mean "configurable by
the programmer"? If so yes, but we still disagree on the mechanisms.
