Perhaps keep default >=0 but when new_variable is called issue DeprecationWarning that the default will change? New parameters should allow setting both >=0 and free explicitly, so that those who want >=0 in the future can set it now and those who don't can also set it now, and when the default will change - no code will be broken, just some of it will explicitly set a parameter which is there by default anyway, which is not that big of a deal. get/set methods on the other hand can just be deprecated directly.
