[Bloat] Update to status of Make Wi-Fi Fast page?

Hi folks, I have been seeing Jim Gettys' post echo around the intertubes. This caused me to look at what we're saying about the Make Wi-Fi Fast project. The "Current Status" at https://www.bufferbloat.net/projects/make-wifi-fast/wiki/ says: --- As of early 2017, we have achieved many of these

[Bloat] Update Cake page on bufferbloat.net?

Hi folks, I saw a blog posting that was enthusing about codel/fq_codel, and I was moved to respond that the state of the art was now cake. But I looked at the Cake page on Bufferbloat.net and wonder if everything there is true, or whether it would be good to update it. https://www.bufferbloat.
