Eclipse often has wizards with both Next and Finish buttons visible. 
They change sensitivity depending on selected options or entered text. 
It is used in such situations: there are other pages with additional 
options or preview, and you can go to them by pressing Next. However, 
you can go with defaults or don't look at preview by pressing Finish.

Other times the only Finish button is replaced by Next if depending on 
selected options another step is required.

All of that is quite convenient, I don't think it would be a good thing 
to prevent doing that in API.

Another problem with this function is that you often want to change 
sensitivity of only one button (Next or Finish), and leave others as is. 
I doubt you ever need to disable back or cancel buttons at all?
