BBN ran them back in the 90s because (IIRC) they pre-dated route reflectors and were impossible to cleanly migrate off of. Other than that, yeah, nobody uses these things. RRs or (rarely) full mesh FTW.

I spent a lot of time debugging an internal fork of an open source BGP implementation (really old quagga.) The confederation code always struck me as being nothing but weird exceptions to how BGP normally worked. I was happy to never hear a network engineer suggest confederations with a straight face.
