It would be easier to have some Boolean values in the decision object, which would simplify recognizing the exact status of a visitor (e.g., whether they are in the "off" variation or the "everyone else" category, or in the concluded/deployed "on" variation). "Enabled" and "variationKey" are not enough to distinguish the above cases.

Currently, they need to check string values and match specific values like "rollout-default" or "deployedtdl" which is not ideal. Booleans would be easier.
