The people who decide what does and what does not go into Ubuntu:

Oh, indeed, toggling the sysctl back will lose your default route, thus
you can't just put it in an extra sysctl statement that runs after it.

Putting an empty file into /etc/sysctl.d/10-ipv6-privacy.conf solves
this partially though.

Recognize what that knob does?

It has to do with the above mentioned file.

Still, all of that can be ignored by systemd, network-manager and other
such things running on a host.
