How strange! I was about to add a comment that I would probably stick to SSE2 or something like that to be sure my code suits as large an audience as possible, including CPUs from more than 10 years ago, ARM, etc.

Case in point: I've been very disappointed lately when I wanted to try Ghostty on my laptop and the binary compiled for Debian failed to run due to an invalid instruction. I don't want to force the same experience to others.
