Wouldn't it be better if diff'ing two perfectly symmetrical dir trees containing the same broken symlinks would produce no output and a 0 return value? Yes, there should be an option to do that, and it should be enabled by default (unless POSIXLY_CORRECT is set).

Dear diff devs,
when recursively comparing directory trees that contain unresolvable symlinks, both matching symlinks make diff senselessly emit a "No such file or directory". Wouldn't it be better if diff'ing two perfectly symmetrical dir trees containing the same broken symlinks would produce no output and a 0 return value?
