Agreed. I've been using dhcp6 here for years, because I want to assign a
static IP to my laptop.
I like to give my laptop a static IP (for IPv4 and IPv6) when at home but
don't care when I'm away from home. Our current options in FreeBSD have
supported my preference for years.

Downstream projects often add, subtract, or replace FreeBSD components. I
too don't understand why a special case needs to be made here.

My opinion as well. I need to see a solid business case why what we have in
FreeBSD base needs to be changed and how any proposed change will benefit
all FreeBSD users, not just one depending distribution. Right now I just
don't see it.
