The solution to the background limitations for now is running as a foreground service. This shows a persistent notification (which can be hidden by the user) but can then run indefinitely. The other option is to integrate this at the system level (via a custom rom, root, magisk, etc.).

The client side implementation of this is still WiP, so it's not used yet in the wild. I hope to be at a point where I can work with some apps on integrating it there in the next few months.
