Good catch. I agree that there may be some merit to allowing access to the underlying buffer, but (a) I agree it should be a separate function and (b) I always like to caution against premature optimization (if a good use case for such a function arises, we should implement it then).

Buffer.toBytesto actually always make a copy like stated in its graindoc comment. Returning the underlying instance of Bytes could lead to nasty unexpected bugs.I'm not sure if we want a way to access the underlying raw Bytes instance or not. It may be handy in some performance critical scenarios. If so, I think it should be a separate function and warn the consumer of the API of risks.
