They usually deal with some Layer 2 protocols (use in special industrial environments), and they want to control where those Layer 2 packets go (output port) depending on several factors like being unicast/multicast/broadcast, coming/going to certain MAC addresses/addresses groups, etc. So while not widely used, there are people doing 'crazy' stuff like that.
