Hi, according to the article here:

Setting Up a Fixed Port for WMI

It states:

WMI runs as part of a shared service host with ports assigned through DCOM by default. Starting with Windows Vista, you can set up the WMI service to run as the only process in a separate host and specify a fixed port.

A fixed port makes WMI easier to use behind firewalls, but in Windows Vista you cannot use scripts that make asynchronous calls. For more information about asynchronous calls

So you would be able to identify WMI traffic easier for firewall rules, but you can't make calls that store results and wait for the collection to complete while executing other code.  These "event sinks" are typically only used for advanced script anyway.
