Yes, indeed. As another example, Apache has an option to only
follow symlinks if they belong to the right person.

OpenWall Linux kernel patch also finds some usage for ownership
of symlinks in +t directories, just in case.

OTOH: I've recently had to fix permissions of a bunch of symlinks
(exactly due to -ow effect); apparently in ALT Linux the default
behaviour of coreutils-5.2.1 is to affect the target though at a
quick skim I can't identify the relevant patch, if any.
