Android will continue to support RISC-V. Due to the rapid rate of iteration, we are not ready to provide a single supported image for all vendors. This particular series of patches removes RISC-V support from the Android Generic Kernel Image (GKI).
Basically, they still support it. But, won't provide a GKI. So, vendors will need to do more work if they intend to run android on a RISC-v CPU.
Pebble was the best smartwatch maker to date. It's unfortunate no one is capable of replicating the features, battery life, and community support like them. I like snazzy fast displays like anyone else. But, I also like weeks long battery life. A pebble like smartwatch with E-ink displays should be resurrected in the near future some day.
