Austin Group Is At It Again, Demands at 11...

Would you mind explaining who's "everyone" and why would we possibly
want to honour that agreement of yours?  Functionality in question is
utterly pointless, seeing that semantics of such symlinks is OS-dependent
anyway *and* that blanket refusal to traverse such beasts is a legitimate
option.  What's the point in allowing to create them in the first place?
