Is /dev/shm the right choice?

I don't actually know what the intended use case of this folder is aside from "shared memory." I'm saying it's okay for now because I am kinda using it to share memory between this program and ssh...? but I don't buy it. It may be a better idea to just have users mount their own tmpfs partitions to be safe, but I don't know if that's a reasonable ask for every user since it requires root.
