[~vagarychen], I believe macOS is POSIX-compliant, and this is what I see on my
MacBook Pro:
{code:none}
david@macbook:/tmp $ ls -ld .
drwxrwxrwt 12 root wheel 408 Mar 30 22:46 .
david@macbook:/tmp $ mkdir foo
david@macbook:/tmp $ chmod 222 foo
david@macbook:/tmp $ ls -l foo
ls: foo: Permission denied
david@macbook:/tmp $ rm -r foo
rm: foo: Permission denied
david@macbook:/tmp $ rmdir foo
david@macbook:/tmp $
{code}
FWIW, I have observed similar behavior on OneFS.

> Empty directories may be recursively deleted without being listable

> Key: HDFS-11557
> URL: https://issues.apache.org/jira/browse/HDFS-11557
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 2.7.3
> Reporter: David Tucker
> Assignee: Chen Liang
>
> To reproduce, create a directory without read and/or execute permissions
> (i.e. 0666, 0333, or 0222), then call delete on it with can_recurse=True.
> Note that the delete succeeds even though the client is unable to check for
> emptiness and, therefore, cannot otherwise know that any/all children are
> deletable.
