Comment (by Chris Rose):

 `nomnom.dev.localhost` does not resolve for me in DNS.

 https://datatracker.ietf.org/doc/html/rfc6761#section-6.3 suggests that
 it's supposed to resolve to loopback.

 {{{
 $ ping nomnom.dev.localhost
 ping: cannot resolve nomnom.dev.localhost: Unknown host
 $ dig @ns-59.awsdns-07.com nomnom.dev.localhost
 $ dig @8.8.8.8 nomnom.dev.localhost
 $ dog @8.8.8.8 nomnom.dev.localhost
 Status: NXDomain
 SOA  23h59m55s A "a.root-servers.net." "nstld.verisign-grs.com."
 2026040400 30m00s 15m00s 7d0h00m00s 1d0h00m00s
 }}}

 From what I can tell, it doesn't resolve anywhere, so I'm not sure what my
 local setup is going to be doing with it.

 At a bare minimum I sure would love it if `--traceback` would show me
 where this resolution is happening, so that I can attempt to troubleshoot
 it in more detail, but I can't get a stack trace out of that command.
