Can someone explain to me why the compiler can’t do struct-field-alignment? This feels like something that can easily be automated.

It can. Rust does.

That requires a way to opt out tho, because there are situations where you need a specific field ordering, so now the langage needs to provide way to tune struct compilation behaviour.
