Why is `ByteVector.toByteArray()` deprecated/internal?

[smoores-dev]

Howdy! This library is fantastic, I can't thank you enough for maintaining it.

Let's say I'm extracting the cover image from an audio file to return in a node.js Response. I'd like to be able to pass the bytes from that image directly to the Response constructor.

It seems that the only way to do this is via picture.data.toByteArray(), which is totally fine. But... why is this marked as internal/deprecated? Is there some other, more idiomatic/safe way to approach this that I'm missing?
