"usually" by whom? "High control over memory" doesn't necessarily mean doing anything "unsafe" with it either. That term could allow for "unsafeness" yes, but it is not solely restricted to that. High control could just mean adding extra annotations about the access, or not having padding in a struct, or specifying the alignment, or many other things, none of which may be classed as "unsafe".
Can’t speak for OP but I also assumed that you were alluding to being able to use unsafe memory management in this part

Since high control usually means being able to do whatever you want (compilers always have to be a bit conservative).
