writable is already set by the streams side, and
there is a handler waiting for the writable side to finish
which already takes care of the other cleanup code that
was previously there; both of these things can therefore be removed.

This requires a full CITGM run.
I would flag it as "backing for LTS", as I would not backport there anytime soon out of caution.

While we are at it, can you add a callback to end()? that's the full signature for streams (https://nodejs.org/api/stream.html#stream_writable_end_chunk_encoding_callback).

Can we move these to _destroy instead and use a stock end implementation?

I think would be a breaking change in light of your comment about not returning this below :/ I’d agree that that would be ideal, definitely.

wow, this differs from node streams, as end  does not return this. We might want to add it to streams too.

I'll send a follow up PR to this one, which will be a semver-major.
