We cannot, because this is a 'builtin' macro, overriding it on the command line is essentially UB.  Additionally, this clarifies that it is an experimental patch, which is less likely to be a concern when we remove it in the future.  That is, the intent is to prevent folks from coming to depend on this in the future.
