I'd exercise caution building on top of it since I don't think Zoom cares about Keybase and I was unable to find any server among their repositories (https://github.com/orgs/keybase/repositories) such that one could self-host after Zoom bores of running the Keybase infra

I used to use Keybase for my dotfiles repo but I thought Keybase was on their way out since being bought?

Which is a shame, assuming it's true. I thought keybase was really innovative in their use of modern cryptography.
