I'm struggling to understand your comments that typical servers do not need swap space and (I think) that systems which swap are broken.
The fundamental point of swap space, going back to its invention, is temporal locality of reference - the idea that in a given interval of time, certain memory is accessed far more frequently than other memory. Are you saying that isn't the case in typical servers? Or that it shouldn't be the case for typical servers? That typical servers should reference all memory uniformly over time and explicitly keep the less-accessed data in filesystems?
(The latter, BTW, was the technology that swapping replaced 40 years ago).
