Respectfully, no, and I don't think we're disagreeing, but are talking past each other.

[edit: I am supportive of (and share) your mindset that it's constructive to go on a case by case basis and look closer at candidates.]

What I'm proposing doesn't necessarily limit cases. Anecdotally, I've hired people that took long breaks with similar burnout stories and upside.

The fact that your anecdotal hiring success story starts with the "burnout" making it to the hiring interview is statistically very favorable for that candidate, the candidate was pre-qualified by the hiring manager, the candidate was interested enough in the position to interview, and it was a matter of fit.

They've already MOVED PAST the gap in your resume issue. Going back to the original comment, you didn't address (as in your original critique) as to whether the candidate had some explanation for their time. Maybe they didn't and still got/passed the interview? Who knows.
