"Most" != "All".
IMVHO it is too strong to say "you don't need to know about [other ones]".
You might say you don't _typically_ need to know about them. Quite possibly
so; but the feature request is for the use case of people who, like me,
find some of the non-Wall non-Wextra warnings to be useful. These
additional flags exist for a reason...
