just implementing it as IPv4 with a lot of bits (i.e. /126s for link 
interfaces, etc).

Yes, there are those of us who want to save number of routes and 
"spending" IPv6 addresses to save on TCAM and convergence time.

Using /112 for link networks to make the last octet ::1 and ::2 for links 
also makes sense from the human perspective.

Well, if y'all want a place to put this hints, I got a whole IPv6y
section over here:
