Yes, the issue raised definitely not prevents a high-performance implementation.

But it's still interesting to ask ourselves if this is not an unnecessary cost?

The concern I have here is that to deal with this question you need very good microarchitecture knowledge about vector-unit, and the author doesn't seem to have them, but he reaches a confident conclusion.

How does one reach a conclusion with so much confidence on a technical subject that one does not know?

Are you saying that only people with very good micro architecture knowledge are allowed to ask questions about the RISC-V ISA?

Whilst the presentation of this as a ‘problem’ is debatable as may be some of the reasoning it doesn’t seem to me that it’s an unreasonable question to ask.

I just think he really thought more about how performance then super low performance implementation.

Its a good blog-post and its a point worth talking about.
