I personally wouldn't rely on that. If a method is declared as static it 
is designed to be static and as such part of the API. The API will not 
change very easily (deprecated first, etc.).

If a bugfix changes a method and it requires the use of another method 
in the same class or the value of a property, from that moment on a 
non-static method can suddenly start to use "$this".
