It’s true that compilers won’t optimise memory layout but I would argue this is an issue for only a subset of the software engineering industry. More important is robust bug-free code with separation of concerns which these tools allow. Remember the first rule of optimisation: “don’t”. The second rule of optimisation: “Don’t...yet”.

Those two are followed by a third rule: "whoops it's too late now, we'd have to rearchitect and rewrite everything and we can't justify the cost"
