I'm pretty sure this has never been true. We should just remove that comment.

I don't think this is the way to explain it. They can be values defined as 
PACKAGE_GROUP_valuename (in which you can specify one or more packages to be 
installed when the feature is enabled - where the packages could be any kind 
of runtime package including packagegroups). The term "recipe" should be 
avoided here.

True. FWIW, this aspect is along the same lines as how DISTRO_FEATURES, 
MACHINE_FEATURES etc. are handled - we check for values contained in them in 
the places in the metadata where we need to be conditional upon those values.

Cheers,
