For example, it's likely that most filesystems would _not_ allow linking

Why? It is just a file that inherits its stat data and is referenced by
a concatenation method of its parent directory. The link will also
inherit its stat data from the original parent directory.
And you might not be able to change the
permissions or date on the named stream either, since it may or may not
have a separate date/permission thing from the container.
You should be able to change the permission and data, but when you
change it, you change it for the whole container.
