would it make sense for the chain switch to be on or off, so there's
only one ribbon connector (for this function) on the back of each
master AND each expander...? to chain one master and two expanders,
you'd have the chain switch on the master and first expander turned
on. or is this too simplistic?

On/Off would be less flexible than On1/Off/On2. Only masters get
chained together, expanders just get plugged in and always operate.
As I said, I still have to work the whole thing out. One diff between
master->master vs. master->slave, is that masters must talk to each
other if random stage selection and direction control are to work
across modules.
