This just proves that Go URL formatting was a mistake. IPv6 addresses existing long before Go decided on how they should be formatting strings. Python has a similar problem with parts of its standard library.

This is what happens when language and standard library designers ignore a spec like IPv6 for a couple of decades.

IPv6 spec was in development until 2017, and it's also weird to have a URL pointing to a link-local address.
