Rather than hiding what is going on with pub/hidden traits, I think it is clearer to simply pass in the MutableBuffer here
If you accept this PR and #1 we can avoid the #allow about private bounds as well

I personally think the code is much clearer and easier to understand if make a function that directly exposes the inner MutableBuffer (which is what the trait does) but mark it as unsafe, rather than relying on non public traits
