For a normal Internet DNS, getting the MX as an additional RR it
certainly is worth it to save one query when mails are being sent.

In wireless LTE networks, NAPTR and SRV are being used for node
selection. I don't know the exact implications but I can see why LTE
equipment vendors would like to shave off a few milliseconds by avoiding
sending multiple queries.
