Heck, you can't tell the kernel to do rename/link/open/unlink
synchronously in-band. This list doesn't care for other OS's. The
semantics FreeBSD (e. g.) offers ARE indeed documented.
This won't work out without kernel support. Portable reliability doesn't
come for free.
chattr +S is bad (slow). bloating all applications to include every
possible brain fart that the random FS inventor let go is even worse.
