Yes, he kind of does. The article was exactly like that for me: "What things needed to be implemented to mark TCP done?" And in video he mention that they split TCP and UDP and he talks about audio needs where if you don't get the packet in time for the speaker you might not send it at all. And he mention this as just only one out of several in the list they had on a board. Watch the video, it's more complete than the article. After watching it I came to the conclusion the article is cherry-picking stuff from the video to make a click-bait-ish kind of stuff.
