But the configuration cost and management overhead is not proportional to the hosts that are served by those interconnections, it is proportional to the number of interconnections.

"If you want to use /64 go ahead, if you want to use /121 go for it, if you want to use SLAAC you'll get a /64 and like it"
Not sure. I for one wouldn't agree with that position, because I don't see that /121 has enough advantages over /127 and /64 - and few enough downsides for general-purpose hosts - to make it a good idea in general.
