It's primarily for tracking purposes. By having a featureflag for each one, we
can easily track whether each feature is active or enabled, which allows pools
that have had redaction bookmarks (or redacted datasets) added and then deleted
to be read by older systems. The two features are also fundamentally
differently implemented, so it makes sense for them to be tracked separately
even if they're introduced by the same code to support the same workflow.
