I don't understand why all these chrome derivatives and firefox don't just band together and extend manifest v3 with some vendored standardised extension that addresses the limitations.
Browsers do that for CSS and JavaScript features already. An extension could just check if the browser supports the "unlimited filters" option and use it if its available.
I have never researched it but heard that the permissions of manifest v3 are much better for privacy.
I am in favor of removing manifest v2 if the vendored extension becomes a reality.
Browsers already have too much complexity, lines of code and feature creep.
