Even my last, crazy long in the tooth, desktop supported this and it lived to almost 10 years old before being replaced.
However at the same time, not even offering a fallback path in non-assembly?

There's probably not any hand-written assembly at issue here, just a compiler told to target x86_64-v2. Among others, RHEL 9 and derivatives were built with such options. (RHEL 10 bumped up the minimum spec again to x86_64-v3, allowing use of AVX.)
