I think it's impossible to declare that, since the symlink namespace is
fair game for userspace do use as it sees fit. 

Emacs and Mozilla lockfiles being but one example...

[dwmw2@macbook ~]$ ls -l .#foo.html .mozilla/firefox/b8v9tyu0.default/lock 
lrwxrwxrwx. 1 dwmw2 dwmw2 44 2009-11-17 19:16 .#foo.html -> dwmw2@macbook.infradead.org.21271:1258450900
lrwxrwxrwx. 1 dwmw2 dwmw2 19 2009-11-17 09:51 .mozilla/firefox/b8v9tyu0.default/lock -> 90.155.92.212:+3756

I wouldn't want to bet that no userspace app has ever come up with the
idea of using a symlink-to-self as a marker for something. I don't think
it's good practice for us to be trying to play games like that.
