Why do you list code density as a potential disadvantage? With changes to the ISA that has already been approved, RISC-V will have the best code density of any significant ISA in real-world code. The article touched on this briefly so it's odd that you would claim this without a source for the claim. I know there's some outdated benchmarks where it's slightly worse than Thumb for instance. But then Thumb isn't relevant for desktop CPUs. The downside for RISC-V for high end desktop/laptop is lack of a large commercial backer (someone like Apple could pull it off, but clearly they've bet on ARM,which was clearly the right choice since RISC-V was far from ready). Lack of the huge legacy of tool chains and software built around x86 and ARM is also obviously a huge disadvantage. But you could have said the same about ARM back in the day. The thing is I'm not sure if the advantages for RISC-V is big enough to take over all of ARMs markets the way ARM has the potential for with x86.
