Oh yeah.

"Just" change the supply voltage. AND the PA. And would that much heat
dissipation even fit in the same space?  OK. Everybody ready to go out and
buy a 28 volt power supply for the new K3S? The range of 12 volt supplies
is way, way broader than 28 volt. The Astron LS35M  35A@28VDC is 380
dollars. Oh, a built-in? Where does it go in the case?

And does the K3S add an internal inverter to produce 12V for everything
else from the 28V?

Lot of expense for a small improvement that they can get with a freebee
change to a late developing gift improvement for the cost of shipping.

What would be a practical way to actually introduce such a change? Lay out
all the specifics involved. Let's see your critical path item by item plan.
It's cheep and easy to just blurt out "they oughta go to 28 volts."
