This is really meant for just the Chinese domestic market, and of very little interest to the RoW. For the Chinese this is a relatively small leap. The Chinese internet has always been it's own separate world, with very little dependence on the US tech giants. Google and Meta have been banned for over a decade, and for almost any significant digital service where the RoW depends on US software/service providers there are large Chinese substitutes.

Although most phone makers still rely on Android, Google Play Store and Play Services are banned in China, so for the domestic market they've always been running AOSP plus domestic middleware. Huawei is now substituting the remaining dependency on AOSP, but the open sourced base layer is really not the valuable part of Android.
