In the past, we've required having an implementation for .mojom changes for the
security team's sake.

What we could do I think is to remember |filters| in a LocalActivityFilter
object probably? I think you could instantiate the object in the same way as
arc::ActivityIconLoader. See components/arc/arc_service_manager.* for more
details.
