In 2.2, at least some of that protection was in ext2 itself. POSIX mandates that a deleted directory has no dirents, so readdir() must not return even "." or "..". ext2 achieved this by truncating the dir to size==0, and by refusing to add dirents to the resulting completely empty directory.
Do we have enough protection to ensure this for other filesystems?
