Re: V extension groups analogue to the standard groups

A question to clarify. You state:
RV32IV doesn’t mandate any FP hardware in the vector unit, whereas RV32IFV means both scalar and vector support single-precision, etc.
This means if I understand you that we need to add F to get F hardware in the vector unit - so RV32IV means V with no F hardware, and RV32IFV includes F hardware.
So for consistency...
What does RV32IV means for M hardware multiply - do I need to RV32IMV to get scalar and vector hardware multiply?
RV32IV means no F and no M hardware? - so I need to explicitly include the extensions I need as V assumes nothing but I?
Or is something assumed for M?
