To enhance filter flexibility: what about allowing us to create our own properties based on WMI queries executed on the client? We will always have special filter requirements in our enterprise environments that will be hard to fulfill w/ static property definitions. And at the end the list of properties will grow to an unusable size. E.g. to support special custom configurations in GPO and Configuration Manager we started to create our private WMI class reflecting special configurations. This allowed us to have GPO WMI filter and CM collections based on that data.
