The network health team (including bad relays) as been rejecting group of relays more and more that do not have their `ContactInfo` or/and `MyFamily` set (for a group of relays from the same operator). These are for safety and health purposes of the network. See the relay guidelines for that. That being said, we should improve the log notice that an operator get when failing to set `ContactInfo` to a warning and adding a sentence that says they might get rejected from the network due to a lack of valid responsive `ContactInfo`. I would argue that this needs a backport for our maintained versions. Please, let me know if not agreeing with that
