I wholefully agree with you. I think it is one thing to implement
useful extensions (and support their use); it is another to present
them as part of the current Standard. 

We used to document `-ansi -pedantic' as GCC's picky mode, it would be
really annoying if, suddendly, we change its meaning and start
confusing our smart extensions with the Standards.
