Actually, no, false is not a value. A true false field is actually a checkbox field and a checkbox field only has a value if it is checked. This is because a checkbox field creates an array of checked items and with nothing checked the array is empty.
Setting required on this field only makes sense if you want to refuse submission if it is not checked for something like “I agree with….”
There are only two possible values, true and false, if you will except either then there is no reason to make it required.
