Thanks to @s3phy again for helping me understand another area where IPv6 is broken in Linux desktop networking configuration tools: connecting to a SSH server to create a SOCKS proxy using the NetworkManager SSH plugin. That thing only checks if the gateway address is a valid IPv4 address :blobpats:
I reported the issue here: https://github.com/danfruehauf/NetworkManager-ssh/issues/130
