I'm sure I've missed your point here. Why is that so? The Rename
refactoring only renames what it should. It's not the old search and
replace, but a smart, context-aware version. AFAIK it won't cross
project boundaries though (or maybe project group boundaries if you have
them)
Or are you talking about changing the public interface? In that case,
then yes, but that's an issue for you no matter what refactoring you do,
either by hand or mechanically. There are a number of issues with
refactoring generally. That's one, the other big one for some people is
that the Fowler refactorings are not thread-safe (necessarily). There
are others.

The extracted method is made protected, if that's what you mean.
Although adding to a public interface is not necessarily bad.

I must confess I didn't see the difference between that and Extract
Superclass :-)

Yes, it is useful, and it works on much more than class names too.
