Should Poky's "tiny-init.bb" recipe be documented?

  Was just perusing the meta-poky layer and noticed the recipe
"tiny-init.bb", which claims:

  SUMMARY = "Poky-tiny init"
  DESCRIPTION = "Basic init system for poky-tiny"

But the poky-tiny distro defines its init manager with:

  # enable mdev/busybox for init
  POKY_INIT_MANAGER:poky-tiny = "mdev-busybox"

and "tiny-init" is not a valid value for INIT_MANAGER, so what is the
purpose of tiny-init.bb, and should it be documented?
