I would conjecture that the integration is for the less schooled and short of time.
Come home on a week night and drop the protein in the bath and a casserole in the oven. Let the machine/machines decide when the table needs to be set.
Frozen casserole and fresh counter protein? Vice versa? A frozen soup and a grilled cheese?
I could write some of the algorithms, pour the vino early.
In an industrial setting, bath A13 paired with oven B12 could be benificial.
Imagine the timing possibilities of pairs and groups with banks.
