Would we actually miss any real emails if our mail server

I don't think it's a good idea to reject any TLDs with open registration.
BTW, Alphabet is at abc.xyz..
Also, what is the current consensus on rejecting messages
from "bare" IP addresses without a name in DNS?
Rather tempfail than reject. You never know if one of the parties
involved is having DNS issues.
(3) NXDOMAIN = No Records = Hard Fail
(2) SERVFAIL = DNS issues = Temp Fail
Connection timeout/Refused = DNS issues = Temp Fail
