You're right but in this case I feel we are moving in the right
direction. While the
behavior will change in some cases this change is only adding well known ipv4
behavior for ipv6 sysctls. In fact documentation briefly mentioned that
net.ipv6.conf.all.* should change all the interface-specific settings
but that was
not the case until now.
