Following the results of Revisit III: Don’t Guess the System policy this meta now refers to an outdated policy.
We have this question about reopening a question and tagging it pathfinder-2e on the grounds that the OP linked to the system-specific rule document. As much as I've been on the side of waiting for explicit mention of a system, I'll agree that this counts as such mention.
Can (or should) we generalize this policy? Are there any problems with doing so that anyone can foresee?
As of 15/06/2021 both answers to this question are positive toward this change with post scores of +20/-3 and +14 respectively. Therefore this change has been added to the policy meta.
