Violating obvious restrictions of the standard is not the same thing as allowing language extensions.  Integer division by zero is always wrong, while allowing integer addition to wraparound for finite-width types is a language extension.  There is no way to describe out-of-bounds array indexing as a language extension.  The Slack discussion is about allowing something that no one has been able to demonstrate is actually bad.
