That audience is sort of immaterial to the argument. If you have a firm that's committed to a frozen image of the platform on a specific date, they'll stick with existing products or modest riffs on it. The same premise is why we'll still see Z80 and 8051 derivatives until long past the heat death of the universe. This is more about why a firm like STMicro doesn't need to freak out too much about RISC-V. There's no reason they 1) can't continue to sell ARM alongside RISC-V for the more change-averse audience and 2) leverage their established reputation in onboard-peripherals, toolchain, and documentation as their competitive edge. Done right, this can be a real "commoditize your compliment" play: they can focus less effort on the boring "core CPU" functionality of their MCUs and divert it for the parts of the product they can offer a stronger case for.
