This allows a user to efficiently watch for services with a common domain prefix. This is exposed in the API via a wildcard character in the service name. For example creating a watcher on "org.mpris*" will match "org.mpris.foo" "org.mpris.bar" and "org.mpris" itself. It will not match org.mprisasdf. Internally the argument match rules have been expanded from a single QStringList to a struct containing args and arg0namespace. This was done so that we can easily use argpath in match rules in the future.
