I agree 99.44%. The behavior of shift operations on signed integers will be fixed in C++20 and C2x, as part of the effort to require twos complement representation. It is a massive potential source of UB in currently standardized C and C++. All the other problems listed remain.

Even after C2x is finalized, people will be using C compilers that don't conform to C++20 and C2x for at least another decade, so you'll forgive me if I don't hold my breath =)
