I ... do not know. I do not know how I came to believe these things. It seems they are false beliefs. The Amiga filesystems were not particularly resilient. I suppose I just finished lying to my parents again. I really should fact-check every damn thing I remember, before talking out my ass about them. I surely live in a fantasy dream world.

Having just read through Wikipedia, though: OpenBSD uses UFS, which layer is referred to as ffs in the userspace. It's potato, potato. The soft-updates should have readily mitigated corruption issues, though they didn't entirely go away. LFS is another component to UFS/ffs, as a formally log-structured filesystem.
