Hubs and Site Collection Archtectures

[kath patterson]

this ignite session sets out the approach that is now being preferred https://channel9.msdn.com/Events/Ignite/Microsoft-Ignite-Orlando-2017/BRK2393

I am interested in what others think about this and if they see any issues?

I like this approach. Less hierarchy - more virtual structure, much like we find in today's business world.
Is there any particular issue you see?

Per our other conversation, the main limitations are that you can only link to one hub and a hub cannot belong to another hub.  

Virtual structure would be nice, but with this it is very flat.
