I feel like adding all of these to the schema without an implementation and/or plan on how to consume them will result in values that are unusable. Silent already has a meaning since there is silent ARP entry data. What do we do if a silent switch is present with that ARP data? Interactive is the default assumption for uninstall ARP command line; when would we use the interactive switch?

If they exist in 1.12 schema but aren't implemented, people can add them without effect until they suddenly light up at some point in the future. This is really the blocking issue to me. I can imagine a path forward, even if it isn't clearly defined today, for all of the switches. But allowing for these to be defined in manifests in winget-pkgs without any validation beyond "the manifest parses" seems very bad.
