ForAnyValue:BoolIfExists

Warning:

ForAnyValue: BoolIfExists is actively confusing. Any operator starting with ForAnyValue will ignore IfExists. IfExists is not evaluated against the entire array, it is only evaluated against a single value at a time, inside the ForAnyValue loop.

This is the kind of thing Jacob would do. Use ForAnyValue: Bool instead so your coworkers don't hate you.

ForAnyValue: BoolIfExists

ForAnyValue: BoolIfExists compares a list of booleans in a request to a boolean in your policy.

To match a request, the context key must exist in the request and at least one boolean in the request must match the boolean in your policy.

You can use policy variables in the value of this operator.
