Why couldn't you use strings instead of buffers when dealing with
textual data? And why don't you need need to worry less about
characters sets if you are doing the charset conversion rather than
the UA? I would imagine you'd have to worry more about character sets
if you take on that burden rather than let the UA do it.

I can see the argument of being a Transferable object. But why
transfer the chunked data between threads? Just do the load on the
thread that is going to interpret the data.

And these methods are dealing with textual data? Note that no-one is
proposing the ability to do chunked-arraybuffer. The question is if we
should have chunked-text as well.
