Re: [whatwg/streams] WritableStreamDefaultWriterGetDesiredSize(writer) cannot in general be used to determine size of chunks read by pipeTo (#938) from Adam Rice on 2018-08-03 (public-webapps-github@w3.org from August 2018)

Even if we assume bytes, we still have to sanity check the value. For TextDecoderStream, I want to set HWM to 1 to avoid adding unneeded buffering to the pipe. But if pipeTo() read 1 byte at a time, that would be pretty catastrophic for efficiency.

On the other end of the scale, the writable might have HWM set to `Infinity` to disable flow control altogether.

I haven't got any good answer except maybe to say that "implementations should choose a reasonable value".
