IPv6 default rule

[Notanial]

Hello, a question to developers.

Could you disable default IPv6 firewall rules, like:

block drop in inet6 all label "Default deny rule IPv6"
block drop out inet6 all label "Default deny rule IPv6"
pass out quick inet6 proto ipv6-icmp from fe80::/10 to fe80::/10 icmp6-type echorep keep state
pass in quick inet6 proto ipv6-icmp from fe80::/10 to fe80::/10 icmp6-type echoreq keep state
pass quick inet6 proto ipv6-icmp all icmp6-type unreach keep state

if IPv6 is disabled
