that's basically x86 without 16 and 32 bit support, no real mode etc.
CPU starts initialized in 64bit without all that legacy crap.
that's IMO great idea. I think every few decades we need to stop and think again about what works best and take fresh start or drop some legacy unused features.
risc v have only mandatory basic set of instructions, as little as possible to be Turing complete and everything else is extension that can be (theoretically) removed in the future.
this also could be used to remove legacy parts without disrupting architecture
