Abused, not used. A number of incredibly dodgy things can be done with
symlinks that point here at one moment and there at another moment based
on the current value of some environment variable, or other hidden system
variable. I cough up a lung every time this topic is raised. Variant
symlinks have caused me grief (Pyramid OSx) and never joy. I hope it fails
yet again to appear in FreeBSD. Just think of the new security holes for a
start.
