As an example we have numerous machines that have had DC installed on them at some point but may not be not in use currently, in storage, etc.

I'd love the ability to tell DC to archive this machine.

I could then uninstall the agent, the machine's data/history would still be searchable in DC by its service tag, but would no longer be listed in patch scans or any other views. Except maybe the SOM View but even there it should somehow be denoted that its an archived machine. Not being listed in patch scans would then no longer have the machine affect the list of "vulnerable machines", or other reports (Except maybe an archived machine report).

Then of course a reinstall of an agent on that machine would bring the machine out of archive.
