It is actually worrying that there will be a push to run a Google-dependent platform on RISC-V's. After all, we know that a lot of functionality is closed into Google Play Services, so that AOSP is to a great extent a bait for being fully tied to Google. Even without relying on closed-source components, you're still relying on Google's interest and good will in maintaining that project.

Instead, it's much more important to promote the "porting", or rather the adaptation, of Linux and *BSD distributions to work on RISC-V. Like with the Raspberry PI I suppose.
