What would you like to discuss?

When reading the doc, I see that when using streams, it is required to call the .end() method to send the request.
Moreover, if options contain a body (or form, or json), then the response stream will be read-only.

Note #2: If you provide this option, got.stream() will be read-only.

And if the .end() method is called while the stream is read-only, it throws.

Is there a way to know that the returned stream is read-only?
(Other than catching this error, or inferring the state of the returned stream based on the passed options)

I would expect the following to work, but apparently writable is always true.

if (requestStream instanceof stream.Writable && requestStream.writable) {
  requestStream.end()
}

I tried to look up in the documentation and existing issues, but couldn't find anything.
Sorry if I missed it.

Also, I'd happy to try to implement something to make the requestStream.writable false when it's read-only.
