Indeed.

As far as processor design is concerned, I believe one of the
problems is that there are fewer and fewer people who can do
both h/w and s/w design competently. This is why I think more
programmers should roll up their sleeves and design a
processor and understand the issues involved, especially now
that programming FPGAs is becoming common.  May be start with
an existing RISC-V core in some HDL, and push and pull it
into (what you think is) an ideal minimalist design. Even
adding a codegen target for such a processor (to at least tcc
or Ken's C compiler) won't be all that hard. I believe this
sort of co-design is what is needed to move past the current
designs. It will likely be some young whippersnapper who
doesn't know what is impossible, rather than one of us
greybeards!
