It's mostly due to performance. It's currently hard (impossible?) to get the same performance as Unsafe when accessing ByteBuffers via their public APIs.
Once the Foreign Memory APIs (https://openjdk.org/jeps/393) stabilize and we update this library to a more recent version of the JDK, we may be able to rewrite it against those APIs.
