The Spaces documentation page has a handy table of how different resources are scoped. However it is silent on most Library items like Step Templates, Script Modules, Packages, External Feeds, Certificates, Tenant Tag Sets, and Infrastructure resources like Workers, Worker Pools, Machines, Accounts, Proxies, and possibly other items I missed
Are Step Templates Space or System scoped?
Are Accounts Space or System scoped?
Could this table please be expanded to cover more stuff?
