Sounds fair.
I agree that the backward compatibility of --no-no-foo is a potential
problem, if any of the actions controlled by "--no-foo" option defaults to
the behaviour when "--no-foo" is given. Among the existing 13 that you
listed, I do not think there is any that tempts any existing user to ask
for negation with "--no-no-foo" form, so I think we should be Ok.
