In my opinion, the real advantage would be to produce ready-to-sell PCBs and offer DIY kits if you want to sell cheaply, but that would limit the customer base even more.
My goal would be to bring the pcb to market and let the end user fiddle with the cooling. Cooling will not be hard as the asic is the sole component on the side of the pcb it is mounted on, so different size heatsinks will work. But a plug and play version would be possible too.
