I put that in there because I'm just one person, working on this in my spare time. I don't think there are any immediate vulnerabilities in KBSecret itself - that's more of a warning that I'll probably be breaking things as I work towards a stable release.
As for KBFS, I can only relay my experience. So far, it's been completely reliable for me - no crashes, hangups, or lost data on what I assume is a lower-priority target for them (Linux).
Have you just been dumping them in a directory, or have you come up with a system for organizing and accessing them?
Most of my work on KBSecret so far has been aimed at my own use cases (single user, multiple machine), so I'd love to hear your perspective on KBFS's strengths and weaknesses in your own setup.
Also using KBFS for some sharing between work groups.
The biggest headache is "groups" -> At the moment, a folder is linked to a specific set of users, which is great, but adding and removing users basically requires recreating and resharing the folder from scratch. (We scripted it easy enough, but its not something the KeyBase UI does).
