Earlier quoted context omitted.
Does the webRequest API deprecation also impact Chromium, and therefore Brave as well? Brave seems like it's willing to backfill in changes to Chromium, but I'm wondering how this impacts the browser overall. I use Brave as my daily driver (with Shields Up and uBlock Origin), but I'm not sure what the actual impact will be when it comes.
It won't effect Brave. Brave is a Chromium fork, not an extension, so have full control over the browser/APIs.
I'm guessing this will make its way into Brave, but their built in ad and privacy blockers should continue to function.
