 > Correct. We should leave `OutboundBindAddress` for the time being. This
 tor-dev thread confirms adding the algorithm to `OutboundBindAdress` would
 not work for at least this use case:

 would fix it, and plenty more use cases. So, we'll leave
 `OutboundBindAddress` aside currently. I don't know, does
 `OutboundBindAddress == Address` unless configured otherwise?

 No, the outbound address is left unspecified by Tor unless configured
 explicitly by the user. So the OS determines the outbound address, which
 can vary depending on the destination (routing table) on multi-homed
 systems.
