kernel metadata: confusing definition of "simplest unit" of metadata

  in the opening sentence here:

https://docs.yoctoproject.org/kernel-dev/advanced.html#configuration

one reads:

"The simplest unit of kernel Metadata is the configuration-only
feature. This feature consists of one or more Linux kernel
configuration parameters in a configuration fragment file (.cfg) and a
.scc file that describes the fragment."

  but that's not true since it seems to imply that you can't have a
.cfg file without a .scc file that describes it. but you can clearly
have that; here's an example from the meta-arm layer that uses only
.cfg files and no .scc files for a kernel append file:

https://git.yoctoproject.org/meta-arm/tree/meta-arm/recipes-kernel/linux

  so how should one read that opening sentence, since it certainly
seems misleading. is it meant to refer only to the yocto-kernel-cache
layer, which certainly seems to adopt that as a *standard*. but that's
not the same as it being *required*.
