A good time to lobby for this might be, well a couple months ago, as they’re producing alpha builds for their upcoming 2.0 release with kernel 4.9 and new Cavium/Mediatek/Octeon SDKs. I just asked about the status in the EdgeRouter Beta forum, in case it finds the right eyes before the release:

My only experience with these devices is the Edgerouter 3/5/X, and they 
have very low performance if you disable offloads (which you need to do to 
enable AQM) and run everything in CPU, around 100 megabit/s of 
uni-directional traffic.

Do they have other platforms where this would actually matter?
