Rive overrides UnityAppController, breaking app functionality

[Nezz]

We recently tried Rive and noticed that it was breaking iOS lifecycle events. This is because the plugin declares its own UnityAppController which takes precedence over ours:
https://github.com/rive-app/rive-unity/blob/c589e52f539a1bbf3004b6c7ac56c523530c9f44/package/Runtime/Libraries/iOS/register_plugin.mm

Would it be possible to switch to a different initialization method that does not break other UnityAppControllers?

I also found that UnityRegisterRenderingPluginV5 was deprecated in Unity 6000.0.10.

I asked the people at Unity and they said that registering the plugin can be done anytime - it does not need to happen from a native iOS call:

Our developers have advised that there are various ways to initialise plugins Plugins are registered before calling the registration function. The registration function can be called from anywhere if Unity is initialised and ready to accept the plugins. For example, you can initialise a plugin from a C# script by calling a P/Invoke function with the __Internal keyword, as long as it's not too late for the scenario in which it's required.
