To delete, yes, but to chmod?  It makes no sense for that to be the case, as
hardlinks would end up being a touch baffling.

[ as root ]
# mkdir foo
# touch foo/bar
# chown user foo/bar
# chmod 574 foo/bar

[ as user ]
$ cd foo
$ ls -ld .
drwxr-xr-x. 2 root root 16 Jul  7 12:51 .
$ ls -l bar
-r-xrwxr--. 1 user root 0 Jul  7 12:51 bar
$ echo rabbits > bar
bash: bar: Permission denied
$ chmod 644 bar
$ echo rabbits > bar
$ cat bar
rabbits
$ ls -l bar
-rw-r--r--. 1 user root 8 Jul  7 12:54 bar
