Although this permits additional diagnostics and optimizations which might be of some value, it is not consistent with long-standing usage, especially for a range of concurrent and sequential algorithms that rely on loads, stores, equality comparisons, and even dereferencing

This is a software-engineering nightmare because all operations on invalid pointers are implementation-defined, even loads and stores. This means that concurrent algorithms such as LIFO Push that knowingly use invalid pointers must have (for example) converted such pointe
