Did Vivaldi? Or Brave? Will uBlock work properly with Mv3 and request blocking?

Of course everything based on Chromium will inherit most of Chrome's decisions, including this one. (Unless they fork their entire web extension implementation and maintain the fork forever.)

Yeah but then "only Chrome" is misleading, when it's actually "every major browser except Firefox".

Safari isn't exactly non-major. By the way, it seems like WebKit Embedded (~resource-efficient Linux port) has regained some steam due to Igalia's work over the last two years or so.

Brave still supports UBo though. How long they can maintain that support is an open question.

Non-Chrome Chromium browsers should band together and support request blocking for Mv3 at this point. It would be one compelling feature that differentiates them from Chrome.

A single engine/implementation deprecated the feature. I don’t think this is particularly misleading in a hacker news context.

Every major browser except Firefox is Chrome
