永住が「取り消し」されやすくなる?2026年の新ルール、申請中の身として不安

I'm mid-way through preparing my 永住 (PR) application and just read that the 2026 revision makes PR easier to *revoke* — apparently even minor offenses (shoplifting, etc.) with a sentence of ≤1 year could lead to a 'downgrade' to another status. As someone who's been careful for years, it's a bit unsettling. Questions: ・does this apply retroactively to existing PR holders? ・does unpaid tax/insurance now count against you too? Not trying to spread panic — just want to understand it properly. Anyone read the actual text?
