In some circumstances, there are not practical.  
I do not have strong feelings about warning by default.

there are reasons we have flags.  That they are "good" depends on your
definition of "good", and is certainly a matter of debate.  The issue
is whether the warning should be on by default or not.  
The same arguments you're making can be used for having the warning on
by default and telling people  to use the -Wno- corresponding flags.
As you can see, the line you're reasoning cannot be  determining.

But it just does that by deciding which flags to turn off by default!
