Hmm. I'd say this depends on what your reaction to the warning is.
If you sprinkle const_casts in the code, nothing is gained.

Perhaps there is some value in finding functions which ought to expect
const char*. For that, occasional checks should be sufficient; I cannot
see a point in having code permanently pass with that option. In
particular not if you are interfacing with C libraries.
