He doesn't want to exclude IPv6 from NetBSD...he wants NetBSD to *NOT

Umm, how can you say that that "didn't break it"? It certainly wasn't 
broken hard, but it was broken. On "anything else like it"...I 
decided to roll a kernel without the IPv6 functionality in it (paring 
down unused options) and was hosed when I rebooted the kernel...The 
kernel worked fine, but I work on my BSD box remotely with the BSD 
box doing auto-dialin to my ISP. When I rebooted w/o v6 support, that 
broke my pppd. I couldn't even use pppd with the noipv6 line in the 
options file. That cut me off from the BSD box until I could get 
there to access it locally. I consider that to be EXTREMELY broken.

He doesn't want NetBSD to be IPv4 only...he wants NetBSD to be *ABLE* 
to be IPv4 only.

Bikers don't *DO* taglines.
