2019-06-03 I have created PR https://github.com/python/cpython/pull/13772 , which adds IPv6 scoped addresses support to ipaddress module.
It is very critical to everyone, who is dealing with IPv6  networking. For example, in salt project they use patched module.
So, it would be very nice to have my changes merged and avoid such a workarounds.
Here is link to the bug - https://bugs.python.org/issue34788.

Please, pay attention to this issue.
