You're not wrong - side channel attacks have been around for forever

  Not all side channel attacks rely on speculation, although I think all known speculation attacks necessarily rely on side channels to exfiltrate information. I'm not an expert but I think that specifically attacking speculation was novel.

    Theo de Raadt was complaining about the possibility 12 years ago. https://marc.info/?l=openbsd-misc&m=118296441702631&w=2 https://marc.info/?l=openbsd-misc&m=118296441702631&w=2

      I don't see any mention of speculation there. Any further pointers?
