I might be asking too much, but for smaller networks, it sure would be nice if the router could be treated as a router+switch by Omada.  Now, I don't know the smarts of what's behind the WAN, WAN1/LAN.....LAN ports, but presumably there's enough to be able to treat those ports like a port on say a 2008?  This would allow the implementation of simple architectures like SSID isolation without the need to add additional hardware (and ports that will never get used.

In my particular case I have an ER605 and 2008P (so 5 + 8 = 13 ports), and I have a WAN connection, a wired EAP225 outdoor, an internal 235-wall and an OC200...so 4 ports total, all of which could have been handled by the ER605...except there was no way to get Omada SDN to do things like configure the ACLs need to isolate my SSIDs.
