I wonder why the old advice was being given if it was so wrong? If nobody understood what to do, shouldn't there have been no advice instead of something harmful?

Anaphylactic shock is scary and peanut fear was a big deal in the late 1990s but actual risk of harm was very low. The guidance was more about the psychosocial burden placed on parents when there was no guidance. Anxious parents have been studied, that mechanism is reasonably well understood and that harm can be quantified.
