What other connector would you use to break out a bunch of pins? These are under a $1 in quantity and can break out 60+ pins per connector. They are vastly cheaper than the corresponding .100" connectors to break these out for the same number of pins. And they have much better signal integrity. An additional advantage to this arrangement is that you can push everything non-essential off the "module" (note that the sockets are on the expansion board--the CPU module is just PCB fingers). Given the current semiconductor supply chain idiocies, this certainly won't hurt. The only other option I can think of would be a DIMM socket and that would be quite a bit more expensive.
