Requirements on toml and other standardized file format use in packaging standards

I’d like to propose a very simple rule for all packaging standards use. Packaging use of standardized file formats must only rely on the guaranteed parts of the standard. That’s it, nothing more to it. The goal here is to ensure interoperability remains as good as reasonably possible. In the case where something is needed beyond what a file format offers, the needed data should be encoded in a way the format can contain reliably, and be handled at the application level.
