What it actually reaches
Blocks, redirects or modifies requests using rules the extension declares up front. Chrome applies the rules itself, so the extension never sees the individual requests — it states what should happen and the browser enforces it.
Why an extension would ask for it
This is the Manifest V3 replacement for blocking webRequest and is how modern ad and tracker blockers work. Compared with webRequest it is the more privacy-preserving of the two, by construction.
How to judge it
A permission on its own says little. What matters is whether it fits what the extension is for: a note-taking tool that reads every page you visit is worth a second look, while an ad blocker that does the same is doing its job. Read the permission next to the extension's stated purpose, and check the host list beside it.
