Address userspace one-liner anti-argument

[js-choi]

These helper functions are simple, and they can be reimplemented easily in userspace. So why standardize them? The explainer needs to address this top objection.

These helper functions are very common. It would improve developer ergonomics, code clarity, and maybe optimizability if they were standardized.

These functions wouldn’t make JavaScript a kitchen-sink language. These are just a few already-frequently-used convenience functions.

The explainer needs to say all this as compellingly as it can.

As briefly mentioned in tc39/proposal-pipeline-operator#233 (comment), when I raised this concern, I personally thought the scope of this proposal would focus on combinatory logic. With the addition of the variadic pipe, compose, and pipeAsync functions, the userland concern, at least for me personally, has been alleviated.
