If someone developed the warning, it could stay forever. The problem is that
someone needs to develop the warning. People working on GCC right now
(including myself) are either not paid to do this or not personally interested
in such a warning enough to dedicate their free time.

People interested in diagnostics (or a boringcc that never takes advantage of
undefined behavior[*]) rather than in optimization should either join GCC or
encourage others to join GCC development to the point that they can influence
its development in the future.
