All I can say is that this behavior is definitely on purpose, although
I don't exactly remember why.

And although it helps you, it could also break things for other people
who expect the current behavior.

Some people definitely expect no IPV6 at all in any way shape or
form if they have not assigned IPV6 addresses to an interface.
