Which is irrelevant to in-market support for that instruction set.

Anyone using software that benefits from vector instructions. That includes a variety of compression, search, and image processing algorithms. Your JPEG decompression library might be using SSE2 or Neon. All high-end processors have included some form of vector instruction for like 20+ years now. Even the processor in my old eBook reader has the ARM Neon instructions.
If anything I'd say that Core 59 is one of those exceptions that prove the rule. This is such a rare phenomenon that when it does happen you can do the work to pin it down and say yup, this CPU is busted - if it was really commonplace you'd constantly trip over these bugs and get nowhere. There probably isn't really, as that paper claims, a "systemic issue across generations" except that those generations are all running Facebook's buggy code.
