The list of restrictions in the user guide seems painful - cannot be used in the same template as nested stacks, cannot start a blue green deploy if other infrastructure would be modified at the same time, cannot import properties from other stacks, cannot export output properties. I was interested, but can't imagine using it with these restrictions.

Thinking about this further, the benefit of these restrictions is in avoiding conflicts where dependant infrastructure is updated in place before the blue green has completed. Lack of inputs and outputs still seems killer though.
