What a coincidence! I've just been playing with Gokrazy a couple weeks ago, and just kept thinking "this is so cool". If you're building some sort of an appliance, and want the least amount of reliance on / hassle maintaining the base OS, it definitely is a viable choice.
It can also run programs that are not written in go, by using a little neat hack to build/embed a binary inside a Go package; this is e.g. how Gokrazy sets up persistent storage: https://github.com/gokrazy/mkfs
I don't think it's for everyone; if you're relying on your base OS / package manager for a lot of stuff, or just want to run Docker containers, I think there are simpler/better ways to set things up. But it's absolutely great at what it's made for; doubly so with the Raspberry Pi's finally being back in stock.
