>> The market they are headed for is embedded...
Are you sure? RISC-V is about to explode in the embedded space. I always ask our suppliers about their RISC-V plans and it's shifted over the last 3 years. They've gone from "what's that?" to the point where they are all aware, some are hedging, and some are going full tilt but not quite at the stage of "here are our offerings". Anyone who is not currently a MIPS user (chip maker) in this space is years behind.
The market they are headed for is embedded, where every cent of the BOM counts. Licensing costs can add up surprisingly fast as part of that.
Server parts are a big step above that - MIPS used to play there, but after a short peak they failed many times over. It tried in the networking and embedded space for a while, but then had its lunch stolen by all the cheap ARM vendors from below, and stomped on by x86 from above.
And then desktop/laptop parts? Unless you are Apple (and even then), pushing a new arch on the desktop is a massive, expensive task, and I can’t see it being worthwhile.
