Well, for me, allow is just to too dangerous and we use it just
to upgrade system files including wstats. Before using it you can
always ask who to the file server. And it's sensible to put an
'echo dont forget to disllow' in whatever scripts you use to install
files. If you fell you really need it, I might change that for you
when I get some time, but I'd prefer not to put that into our regular
kernel.
