As a general rule, when recording a scoped metric, the corresponding unscoped metric should always be recorded as well.
As an optimization, scoped metrics are representated within this class only by their entries in the @scoped Hash, and it’s up to clients to propagate them into unscoped metrics as well when instances of this class are merged into the global metric store.
