One might ask that, but one would be barking up the wrong tree. :)

It's true that if you don't know what the mount point /dev/shm is, you might
think that you're giving up disk space, but if you know that it's not a disk
device at all and realize that it's taken out of RAM as needed up to the
defined limit (which as you can see defaults to about half of your physical
RAM), then it *does* show you something to make you feel better.
