Peer endpoints are the only part of the information displayed by wg
showconf which change dynamically. Wireguard doesn't cache the original
endpoint specified by the config (if any), so it's not possible to
display it.

I'd suggest you set up your provisioning software to ignore the
endpoints in "wg showconf"'s output if(f) the configuration file
doesn't specify endpoints at all.

If the config file does contain an endpoint, it's probably a good idea
to compare it to the endpoint reported by wg showconf.
