This document servers as an explainer of an experimental feature which was most recently committed to chromium [codebase](https://chromium.googlesource.com/chromium/src/+/d8e49fe9a8374c236010d75874c082e9701543fb). The state of the proposal is not complete as there is still a critical open questions regarding the correct implementation and behavior for cross and same-origin contents.

All suggestions and ideas are most welcomed!

Addressing comments, fixing typos, and more importantly renaming the feature from `document-stream-insertion` to `document-write`.
