It disables NT ACL manipulation via chmod, chown and chgrp.

I have different users on my machines for various reasons, and
permissions are sometimes a problem. Concrete real-life example: on my
laptop I have a "presenter" user who has extra-large fonts, so that
folks can see code samples etc. during presentations. However, the code
samples themselves are created and edited using the normal user, and
often end up inaccessible - i.e. read-only - to the presenter user.

I have a simple utility called reset-permissions that uses chown and
chmod to recursively reset permissions to a known good state in the
directories specified as arguments. This works well enough that I don't
have to panic over file rights in the middle of a presentation.

I could write my own chown and chmod, perhaps in terms of cacls, perhaps
with custom utilities for more precise ACLs. I'd rather not have to
reimplement those utilities though.
