I don't see how a warning-specific option could be an "excuse".  It
can solve the problem you attempt to solve as well as what you
propose.

And if you think that referring to my views as "excuses" somehow makes
your opinions more convincing, you are wrong.

I don't see how the discussion I suggested could be viewed as
"discrimination".  I feel that there's some fundamental
misunderstanding here.
