Okay, I haven't looked at the implementation to be honest, but am just trying to understand the different use cases of this first. I just seem to be missing or not understanding why fixed/scalable is an option to only vectorize_width, why not to vectorize(enable) or just a separate one like vectorize_scalable? By making scalable/fixed and option to vectorize_width, you can't toggle this for other pragmas like interleave(enable) that enable vectorisation, which would be inconsistent? It also seems to be more work to me to do this first for vectorize_width, and then fix up other pragmas later. But I might be missing something (obivous) here.
