It's certainly comfortable to argue this way if your opinion is that of 
the majority. In the library submissions process [1] it is acknowledged 
that a majority vote needs not to be the final criterion. I think it would 
be better to work towards a consensus. The consensus here could be: We 
acknowledge different styles of programming and therefore different 
expectations to the compiler. Some programmers consider it a bug if 
'length' is defined on tuples, other ones consider it a useful feature. In 
order to serve both sides we add warnings for those who want them. But 
these warnings should be bundled together with the instance additions and 
not deferred indefinitely.
