Yeah that’s my thought. The main benefit to this is High Availability. You’re not going to get compelling scale-out performance, but you can protect yourself from local hardware failures.
Of course, then you have to ask if you need the density. There are lots of ways to put Rpi in a rack.. and this approach gives up Hat compatibility for density.
For example, I’m considering a rack of Rpi with hifi berry DACs for a multi-zone audio system. This wouldn’t help me there.
