Third parties loading

Just a question to early understand if this project can help with third parties loading. If I want to download a tag manager container, for instance, could the web worker completely assume control of loading all tags or I simply can't avoid it being done on the main thread?
Could I isolate third party loading on the web worker?

The issue names no files, tests, or entry points. First clarify whether isolating third-party tag loading in the web worker is supported or desired, and define the expected scope; done would be a documented feasibility answer or an agreed implementation plan.
