If you specify "order":"ignore" for all fields in a record, then, yes,
all instances of that record would be equal.  I cannot imagine a case
where this would be useful, but I also don't see how this would violate
the equals() contract.

The default for fields is to behave as if "order":"ascending" is
specified.  Records are equal if all of their fields that are not
specified as "order":"ignore" are equal.
