Well, if I compare Bluetooth (often doesn't work for no apparent reason) to WiFi (works, and when it doesn't there are comprehensible reasons) - this one might actually work. Mesh networking is very hard to do right so I can imagine how well Bluetooth's attempt worked. Probably might as well not have it at all level.

Edit: I was thinking of more dynamic and larger meshes - those are really hard. This standard seems to have a smaller scope. It's still more difficult than one-to-one.
