Yes. In my experience, the biggest backward compatibility problem is when 
you go from a very limited special-purpose something and slowly and 
progressively turn it step by step into something tremendously general.

Think, say, of XML being used to specify a programming language.

If you have lots of defaults that nobody ever uses, or lots of syntax to 
indicate old-style vs new style, you're probably screwed.
