My read is that whatever subset of the ecosystem bcachefs-tools just hasn’t stabilized. Presumably it will, but once everything is functionally at 1.x even if they don’t reach it officially this will be become a non-issue.

That said, having dabled in rust there’s a temptation to name breaking changes to improve ergonomics because the type system is so expressive. I almost wonder if this is an argument for simpler type systems to reduce churn.
