This same point is made in threads discussing how wayland protocol is 16 years "old". I think it's different if the system starts out as a research project rather than a commercial project, because the time until a usable implementation is much greater. For example, I would say that riscv is "newer" than loongISA/loongarch despite being slightly older in a literal sense.

If you look at an arch like x86 or ARM it was designed right before chips were released, and then extended over time. The same goes for the X protocol, it simply extended previous versions.

If you are designing something from the ground up to avoid the inherent problems of an existing system, it is reasonable to take time and research design problems to make sure you don't recreate the same issues (which would defeat the point of the redesign). It doesn't compete on the same time-frame as an extension of an existing system.
