On the other hand, it makes changing things which are visible to add-on 
programmers hard to impossible.  This, in turn, encourages developers to 
hide the code befind an API façade to re-gain some flexibility.  I've 
worked woth some projects which follow this approach (notably Dokuwiki and 
Firefox), and I found it to be a harmful for both sides.
