I hate to say it...but in my experience, this has been exactly the case
with soft updates and FreeBSD 4 up to 4.11 pre releases.
Whenever something untoward would happen, the filesystem almost always lost
files and/or data, usually just files though. In practice it's never
really worked too well for me. It also still requires a full fsck on boot,
which means long boot times for recovery on large filesystems.
