> Non google browsers didn't only disable it, they removed it completely.
They set the toggle to false and deactivated any of the options to turn it back on. That's very different from removing a feature (or maintaining a legacy feature).
The only code they changed was UX-related and a single default.
Google has a lot of control over chromium, but I don't think its even close to how gimped AOSP is compared to Android google edition.
