Additionally, AFAIK, none of the major repo hosting services (GitHub, gitlab, Bitbucket) support sha-256 repos.
GitLab has been working on integrating SHA-256 support for a while. According to this comment[1], there's only one major blocker left (which seems to be completed at the time of this comment) before they can start testing SHA256 support on GitLab.org.
