One of the immediate benefits of using a /126, is that it's not a /64! Also, a /126 is the smallest non-64 size with the highest likeliness to get the job done from an interoperability perspective (not the /127). Another example: when you use a /120, the advantage again is that it is not a /64, and you can make a bunch of routers talk BGP with each other on a layer-2 segment. This is why /126, /125, /124 etc end up being used. An Addressing Architecture that does not admit this has been common practice for 15+ years, is disassociated from reality and thus inconsequential and no good. It does not follow that because you don't see enough advantages, the idea and practice are bad.

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.
