The expiration date of the temporary ed25519 signing key is included in
the server's descriptor afaik, but there's no way to know if a relay has
OfflineMasterKey enabled or not. We could add this extra info but I
would disagree since this will advertise which relays have this enabled
and which not.

The system is designed in a way that you should not use OfflineMasterKey
if you want to leave your relay unattended or don't have time to renew
keys. A simple script installed on the relay and executed by a cronjob
can determine the expiration date of the ed25519 signing key and send an
email when there's less than X minutes/days remaining. I don't think
this should be a network wide default.
