Request for system binder wrapper like Shizuku

[auag0]

I want like the following functionality:

IPackageManager pm = IPackageManager.Stub.asInterface(new RootBinderWrapper(getService("package")));
pm.getInstalledPackages(0, 0);

For reference, Shizuku implements this approach in the ShizukuBinderWrapper class, which you can find here:
https://github.com/RikkaApps/Shizuku-API/blob/master/api/src%2Fmain%2Fjava%2Frikka%2Fshizuku%2FShizukuBinderWrapper.java

Can't you get the 'package' service in the root service and retrieve it with aid?
