For a language that _competes_ with C, caring about how semantics map to hardware instructions is absolutely within the domain of concern. It may not be a top priority, but if you _ignore_ it too long, you'll make uninformed high level decisions that prevent entire classes of important low level optimizations without extensive re-thinking. So just do the thinking upfront and save yourself and your community the hassle.
