For present stdlib capabilities and types like vector that aren't totally bounds-checked, the aim is for these options to generally be bounds-checked when identified as from code Together with the bounds profile on, and unchecked when identified as from legacy code, possibly making use of contracts (concurrently becoming proposed by a number of WG21 customers).
If We have now a million strains of latest code, the idea of “just modifying it suddenly” is typically unrealistic.
