Not really in any particular order. Some are more logical than others.
- TextDecoder / TextEncoder
- URL
- fetch() (unclear yet how we are going to namespace this, CORS behavior also does not make much sense outside browser context)
- Worker / SharedWorker (and all the port business, structured cloning is on its way already; would require events to be ported too)
- window.btoa() / window.atob()
- window.setTimeout(), …
- ImageBitmap
- EventSource
