What if the access to that variable was forbidden for reasons you never
foresaw? What if the class author decide to remove the variable in the next
version of the class, because it's not an interface, but only a part of the
class implementation?

Yes, that's how it works in the open source. What's wrong with it? You
don't need _this_ class, because it's functionality doesn't fit to you. So
you take the source code and write another class, doing exactly what you
want it to do.
