Pretty much this. There is a significant learning curve to kubernetes (or similar, I guess?), but it’s a handy skill to be familiar with. If things basically run but with degraded performance on one raspberry, there is no real need for a vertical performance increase. Adding the second will provide almost double capacity, with some HA added for fun.
I suspect I’m pretty much the only market for this thing. I can play while in bed, which is where most of switch gaming currently happens. The price is probably reasonable for what it cost them, but they need to explain why anyone besides me would want one.
