Preparing the ability to use mount points is just loading a table from
the /etc/fstab file.  There isn't checking involved and especially no
checking of the ACL of a directory.

Additionally it's not even possible to do what you want.  The ACL
of the share does not contain any hint about the share permissions,
and the share permissions of a remote share can only be requested
with special permissions.  Normal users get an ACCESS_DENIED when
trying to request this information.
