There is still plenty reason to have carbines chambered in 5.56, since a Grendel load that is capable of replacing the 7.62 NATO for range and penetration will have all the effects you don't want at close range:
Too much recoil
Too much penetration for Close Quarters
Too much weight penalty on the rifleman
You would need a separate light loaded round.
