I think the problem is that it already is really easy. I feel like it'd be hard to simplify the interface of something like UniFi's AP series and still keep the number of knobs it gives you. And you almost certainly will never simplify it to the point that people will stop making youtube bandicam free edition tutorials on how to port forward your minecraft server.
The UniFi range is very easy. The Edge series (such as EdgeMAX) is slightly less easy, but also more powerful.
Easy and secure are not always a good match though. Take UPnP for example. Disabled by default on my ER-L, it can be enabled, but its ultimately insecure. And ultimately, HTTP over SSL could download payloads.
