Perhaps -- until your httpd is compromised via a buffer overflow or
simply misbehaves due to a software or configuration flaw, then the
assumptions being made about its use of pathnames and their security
properties are out the window.
Without security labeling of the objects being accessed, you can't protect
against software flaws, which has been a pretty fundamental and widely
understood requirement in general computing for at least a decade.
