> The intuition here is that directories are a shared resource for their direct children and must therefore serialize concurrent directory-modifying operations, causing contention.
why do you think this is true?
i've never heard of anything like it
directories are inodes on a file system, they are in no way "shared resources for their direct children", and there is no concept of a "directory-modifying operation" which contends with operations on any file (or directory) which is a "child" (subdir, sub-file) of that directory
your claim is totally bizarre to me, afaik it's nonsensical, but i guess i could be mistaken
