The Academic Free Licenses versions 1.0, 1.1, 2.0, and 2.1 are marked as OSI approved in the SPDX license list, however, these licenses do not show up on the OSI list of approved licenses nor in this repo.
This was discussed in the SPDX license list issue #1327
Based on this comment, earlier versions were approved by OSI.
Based on this comment, OSI does not "unapproved" licenses once approved.
Suggest we add the older versions of AFL to this repo to be consistent with SPDX.
