Likely because there are known limits at the amount of heat that a semi-passive cooling solution can dissipate from a single socket. Dividing the heat on two or more sockets the OEMs have an more easy life to think about an efficient semi-passive cooling via copper heatsink under a moderate air flux inside a tiny server box.

You can follow IBM with some exotic solutions but this is not absolutely the case. Over 200W/socket the heat dissipation become very serious to manage in actual popular server boxes. Finer the process utilized the thing become even worse cause the stellar power density on die, and Fins do not help at all.
My bet the shrink game will be stopped mainly by power density rather than by yields issues.
