The DNS NAPTR is also turned off by default, which should be on, based on RFC, iirc, but that adds extra DNS query and slows down everything as most of services I saw so far do no relay on NAPTR.
It is OK to have NAPTR lookup off by default, but if it is turned on, I don't see any point why order value is not obeyed by default. For example, if TLS preferred, that preference should be respected for security reasons.
