TFA argues developers add it left and right, unless someone memorised all the rules. Since reportedly it's not possible to memorise all the rules by a single human, then you either "simply add undefined behaviour", or limit yourself to a subset of C++ that programmers do actually understand. Which is a solution I see in many codebases: to limit a set of permissible constructs by a style manual.
