I agree: see also:

What's Gödel have to do with it at all?

(I don't necessarily agree with the rest of your mail.)

as much as possible, interfaces that are not the same about things that 
are, should be transformable by a function that takes an interfaces and 
turns it into another interface. This is so that people can guess how a 
class works, from the knowledge of how a similar class works. It can save 
on the amount of help files too. Ideally, we'd save on the number of 
classes, though.
