Well, it changes the code (e.g. it could allow / prevent some optimizations) and that could mean that the shader gives somewhat different output when there are numerically unstable float computations involved.
Very unlikely to be of concern in practice of course, but leaving a trail in the log should be valuable if that ever happens.
