I never mentioned anything about 1.2.3.4.  Not going there yet.

Yes, but IP addresses still work (sort of) fine with TLS.  Still not
going there, yet.

If bob.example.com is not an NTS-KE server then what is the point?  Why
does the example mark bob as an NTS-KE server?

Since this is upward from the existing ntp.conf then ntp.example.com
must be the NTPD sever and bob the NTS-KE server.  But once you specify
an NTS-KE server you should not specify the NTPD server.
