@aledsage: Revisiting this, `DeferredSupplier` simply restates the contract
of (Guava) `Supplier`. While superficially redundant, it may offer a (tenuous)
distinction between "immediately resolvable" and "deferred-ly resolvable"
quantities. Seems weak though, and potentially *very* confusing for users.
