What about signing my git commits to prove I authored them? As far as I know, no alternative exists for GPG there. If it did, we'd need also tools like Github to support it before it's adopted. I do see GPG being replaced in so many areas, so I'm not opposing the OP. Just saying that I use it for signing commits every day and my engineering team is required to sign all commits; Github helps us enforce this by requiring that PRs contain only signed commits.
