I'm curious how this came to be:

I'm not at all in the know about this, so it would not even occur to me to test it. Is it the case that if you're optimizing Linux performance you'd just try whatever is available?
almost certainly bottom-up: some eng somewhere read about it, ran a test, saw positive results, and it bubbles up from there. this is still how lots of cool things happen at big companies like Meta.
