That's the other way around where, where an old OS can't read a new partition. I don't think a change in filesystem, would ever be made without support for the old version being provided - at very least as a kernel option. For example COMPAT_FREEBSD4 provides access to filesystems created in version 4 and early releases of 5.x, and it's compiled into the 5.4 generic kernel by default.
