"Conclusion The RISC-V architecture was developed in classic startup/academic style: innovating quickly and avoiding too much investment in long-term engineering"

But this is not a conclusion in any sense. This is the premise of the entire RISC-V project. Because RISC-V is just an abstraction to teach and learn machine-level aspects of programming regardless of the specific processors available on the market. Donald Knuth has the same, MMIX. In addition it is difficult to say what innovations there may be in the RISС processor instruction system.

Well...
