I'm *not* saying I'm using RISC-V.  I'm saying that I am compatible with
their standards, but I'm not RISC-V.

so use the phrase "V-CSIR RV64I compatible" instead :)

I don't even do that.  I say that I provide support for the RV64I
instruction set and a proper subset of the privilege specifications.  Other
ISA extensions might be coming in the future; but on the whole, my
processor is the 530x0 family of processors.  The 530x0 is RISC-V
compatible, but not conformant, in exactly the same sort of way that Compaq
machines were IBM compatible, but not IBM clones or certified.
