But that doesn't make pointers themselves complicated. Most of the C community agrees that strict aliasing assumptions are more trouble than they are worth.

Strict aliasing isn't the root problem here, because Rust, which doesn't have C-style strict aliasing, would similarly exhibit the same theoretical miscompilation in the absence of provenance.

strict aliasing is an example of questionable optimizations from hard to verify assumptions.
