But why bother with the isolation?

NO RATINGS
An interesting post, and I am trying to imagine why a constant voltage mode would be needed. How about just a voltage limit?  But the big question is about isolating the devices from the line. Why bother? present systems do very well in a non-isolated mode. Just add that warning tag, " Output is not isolated from AC line, warning, shock hazard". The other thing will be to always have the LEDs separate from the drivers, so that when one fails the whole does not need to be replaced. Less convenient and more complex to implement, but much more economical.
