How quickly does the industry move? Would there be any value in a 2006-era instruction set? How would you even start making sure you didn’t infringe on any patents that came after 2006?

The first version of RISC-V was released in 2010. It was based on work done at Berkeley in the 1980s (RISC versions one to four).
One reason that RISC-V has so many optional extensions is that you can trust the core is very likely to be patent-free (because everything in it is documented to be older than 20 years) and just evaluate the extensions you need.
