I think the thing to remember is that these bypasses still access the service side of the shops, so it's unlikely they'll be open on any sort of permanent basis. So they need to be somewhat flexible. So there will be some elements to make it more presentable to guests, but I'm sure there will be two position gates to control access to various things....so when in guest open mode, it will make it easy to fence the guests in.
I don't think you'll see any improvement on the entrance ports though, as opening that bottleneck might just move it out to the tap styles.
