ForAllValues:BoolIfExists

Warning:

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

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

ForAllValues: BoolIfExists

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

To match a request, the context key can be absent, but if it is present, all of the booleans in the request must match the boolean in your policy.

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