Sounds like an opportunity for someone to sit down and write one. The API and docs for it are fairly palatable and offer some very reasonable guidance on things like exponential backoff.

It still doesn't mean that they're going to be able to go without a persistent notification if they want to run their own background service, but that's a change that everyone is required to deal with. "Secret" background services were abused egregiously by bad actors and sloppy coders alike in the past and it's time for that to stop. This carp some people are floating about it incurring "warning" is nonsense--if they looked at the developer docs they'd see how easy it is to avoid that happening.
