File bugs for the apps that you *know* could use the optimization.  Make
sure the code actually can use those newer instructions and that the
compiler actually does any auto-vectorization for the code in question.
Provide benchmarks proving that performance increases instead of simply
blind and likely incorrect assumptions.

Or maybe that many people are clueless.  Thankfully most of them are as
rude and obnoxious as certain others.
