No, it doesn't. Bill was asking about implicit permissions granted to the
owner (creator) of a directory, not a volume.
Also, please do not add configure-time options to control behavior. New
configure-time options are normally appropriate only when they affect
things which must be decided at compile-time, such as which platform we're
building for, what directory layout to use, or which external packages to
use. From time to time you will see a configure option to enable a feature
which represents a substantial code change which is not yet ready to be
included by default, but those cases are exceptions rather than the rule.

It might help to start with the idea that AFS is not other filesystems, and
has its own semantics, rather than being surprised every time AFS's
semantics are not the same as those of some existing filesystem...
