Thanks for explaining.

Is auto-removal of the non-registered parent directory a workaround for
packages that make directories and do not declare them in PLIST?  It
seems like if there is an empty directory already, and a package
installs a file in it and then the package is uninstalled, that
directory should not be removed.

Or is there some other reason why removing directories is the right
thing to do?
