In particular, if your site has 256 PTP links, you can convert from /30s to / 31s, save 128 IPs, but then trying to *actually use them* effectively outside your AS ends up sounding like this: "Eat your Brussel sprouts. Don't you know there's kids starving in Africa" "OK, you can send my sprouts to them..." :)
