I get that they're "public" keys, but I was surprised to learn (and from somebody other than github themselves) that ssh public keys are just available at that github.com/username.keys URL (without there being an option to disable it, it seems?). Did most people already know that? Probably fine but just surprised. Just tried searching their authentication docs [0] and I don't get any results for "public key url" either

We've implemented a DID method based on this!

How does it work from a client perspective? Are there any browser (or browser plugin) supporting it yet?

On paper it sounds pretty cool, i would dare say the only interesting application for DID i've heard so far :)
