By the way I removed the if condition and added nothing in its place, just to see what would happen. I see a lot of these messages, I did not investigate where they are coming from and why they are emitted. They go away when I rename the interface back to swp0.
Looks like it's again related to dhcpcd. If I rename the interface while it's down, the link-local IPv6 addresses don't get endlessly deleted as they do if I rename it while it's up. Also, if I live-rename the interface while dhcpcd isn't up, that behavior disappears too. Still not sure why it happens.
