It is a newer pattern so I would expect there is friction. The problem is if there is any serious amount of depth to your app you need to overflow the access to the other features somehow and this is, in my opinion, a good way to do it. I think that given enough time and it becomes a pretty common pattern the pain of discoverability that the article brings up will not be an issue. Most of the arguments brought up in the article are only valid in apps with focused small sets of functionality. I think the move Google did with the Google+ app is a good(bad) example, they got rid of the hamburger menu in favor of a combination of several menus (bottom menu with a expanded menu at the top). I find trying to find things in this new app painful. The hamburger menu excels as a landing point or a dashboard access to functionality.
