RISC-V is far past "couple of maker boards" now. The last year has seen a lot of activity. You're right that a number of mainstream software packages are still work in progress, for example V8 doesn't target it yet. But RISC-V is thriving in other areas like industrial controllers, and Alibaba Cloud just announced a few days ago they are using it in a new server processor, positioned as an eventual competitor to AWS Graviton. Topically: Nvidia uses RISC-V in some GPUs as a controller (not the GPU core). Not sure if those are released yet, but they gave a presentation on it at a recent RISC-V meet-up.
