tracked property
Tracked is how many callers this scope holds state for right now, and Ceiling is the most it may hold. Tracked == Ceiling is the fact a bound that binds cannot hide.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
