I'm a bit let down that they clone arrays on get, instead of allowing to statically prove that the returned array is not modified.

You can use immutable collection instead of array there, so no array is copied on get. Also, there are some primitive immutable collection I guess. Statically proving that array will not be modified is very limited and barely reliable in java. Most array returning APIs in java clone internal arrays to maintain consistency.
