Review comment:
Yes, I think chopping up the byte stream at arbitrary points has many more
subtle complexities than splitting things up at element boundaries (for both
the data stream and iterable elements), as well as being a non-trivial change
to the public API of coders.
However, thanks for bringing to the list. I'll continue the discussion
there; let's see what comes of that.
