Neither a simple boolean "restricted" flag nor a tiered "restriction level" system are really sufficient.

For example, customer credit card numbers should only be passed to the card-processing facility, while your SQL DBMS connection password should only be passed to the database. They should both be marked as "restricted", but you don't want to let them cross-contaminate. (Unless you explicitly enable that.)

Instead of a flag or an incremental level, something along the lines of categories might be more useful -- this data is restricted as "customer private" while that other data is marked as "server internals", and only channels/objects which are approved for that category can access them.

More generally, you might want to look at Capabilities for a more sophisticated way of building an access control model.
