It turns out that grace periods (called a "redemption grace period") weren't proposed until 2003. I'm not actually sure when this process was approved by ICANN - sometime between 2003 and 2013. The latest version of ICANN's registrar accreditation agreement, in 2013, includes grace period provisions. https://www.icann.org/resources/pages/approved-with-specs-2013-09-17-en https://www.icann.org/resources/pages/approved-with-specs-20...
