Fedora 6 default permissions for roots home

[Shams]

Hi,

I installed Fedora 6 and noticed that the directory /root (home of root)
has the default permissions r+x set for group and world.

Can someone enlighten me why this is the case, isn't it best by default
to have it no permissiosn for group and world?

I mean shouldn't /root have "just" the rwx permissions set for owner
and for group and world permissions only enabled by root if it needs
to be?

Thanks
Shams
