There is talk of adding poly-instantiated directories to SE Linux which
will give similar facilities. I'm not aware of any code release yet
though.

Yes, that solves many of the issues related to users attacking other
users via sym-links. But it doesn't entirely solve the issues related
to attacking the administrator processes. It's a fairly standard
practice for the administrator to inspect the files of a user and modify
them on occasion. This means that the admin has to work inside the
mouldy directory.
