There are no obvious changes to a widely used programming language standard.
Even small changes often require years and many revisions to be accepted - burnout is common. You would need to build a consensus that this change is desirable - that's highly unlikely at best. Strict aliasing has been widely implemented since the 1990s and many compilers benefit from the rules; many compiler vendors are on the committee. You'd have to convince them that they should make their customer's code slower.
What might be achievable, however, is some kind of technical report on undefined or implementation defined behavior. Many compilers have options that allow programs with some undefined behavior to behave as the user would expect. Microsoft's C and C++ compilers, for example, don't enforce strict aliasing and allow some forms of integer overflow in loop conditionals. There would be substantial value in defining a common profile for these options. It would still be an uphill battle to get it through the committee, though.
