I would like to see the 0BSD license cataloged in the appendix. Without it, the downstream Licensee project mis-detects 0BSD as the ISC license. The 0BSD license is basically the ISC license without requiring a copyright notice.

The 0BSD license meets criteria 1 and 2 for adding a license according to the CONTRIBUTING.md, but I'm not sure if it meets criteria 3 (at least 1000 repositories). It is difficult to verify if criteria 3 is met because 0BSD contains more or less a strict subset of the words present in the ISC license, so I was unable to construct a search query that matches only 0BSD but not ISC.
