If sometime in the future we decide to store something in the index that is important, we'll definitely want to remove the index, because whatever it is will be both important and -wrong- for a new parentless commit, since a new root should have all the default values, not values acquired during the other history in the repo.
On the other hand, a builtin command of that sort probably ought to make sure that there aren't any uncommitted changes before doing this. And it should probably be called "git checkout -b name -N", since it makes it your current branch, rather than creating it like "git branch ..." would suggest.
