802.1X is very widely used in GPON and DSL networks and I haven't heard of it having any issues. I'm not understanding the reference to WPA and local devices, since I think we're talking about the WAN and not the LAN interface here?

TR-069 is a management protocol (that goes over HTTP, using TLS for security), and not an access control mechanism. I suggest it be removed from this list.
