I just don't think having 'gotcha' rules the compiler exploits to do whatever it wants regardless of programmer intent is a good idea, and that's how C/C++ treats UB. UB should be a compiler error and force the programmer to specify what they want the result to actually be so there are no assumptions on the programmer end and no surprises from the compiler.
