Are we blaming the spec and the author of the post for trying to conform to the checks, instead of blaming Adobe or Kobo for using 16-year old technology that ISN’T spec-compliant? -.-

Yes. sometimes specs are badly designed. Targeting a constantly moving goalpost for a spec mainly implemented by embedded devices seems to me like, best case, questionable judgement
True, but that doesn't get Adobe off the hook: CSS mandates that unrecognized declarations should just be ignored, so the worst that's supposed to happen in the average case is some layout funkiness - not catastrophic failure.
