I agree and there is a very hand-wavy slide in the deck about another
"meta" level above the layers...  To try to be more concrete: I think
this means basically a top level file, likely also using YAML syntax,
that defines the existence and purpose of various Layers (including
characteristics such as what suffix files of that type should use).   

Just like for the VSS concept in general, I'd expect that idea, if it
gets properly defined, to be usable both for common agreements about
layer types (specified in VSS documentation and thus shared in the
industry), and proprietary layer definitions inside a company (because
collectively we might not envision every possibly usage of this).
