This may sound silly, but this makes a real difference. Until this, it was not possible to run standard containers like Docker or Podman in an initramfs without ugly tricks (like using chroot instead of pivot_root, or mounting the root over itself before starting init). This makes the initramfs rootfs un-special. Aside from being volatile, but this is a design decision.
