I wouldn't mess with W. On media, we work to have zero warnings with W=1.
However, W=2 (and W=3) is almost unusable: lots of complains about 
signed/unsigned mix and other things that usually are ok. With gcc 8,
the amount of warnings with W=2/W=3 at core kAPI functions makes them
useless.

People will very likely ignore or miss deprecated stuff if we
place it as W=4.

Perhaps we could add a D=1, in order to point for deprecated stuff.
