I think going for variable length is a Bold Move, and am not sure I like it for an ISA that otherwise is trying to be conservative. I'll be more optimistic about it when I see SVE (a) on more than one HPC machine and (b) implemented in a variety of widths. I'll be impressed if it works, but I'm not going to be impressed ahead of time with it while it's an aspirational design because it has aspirations.
