Got here from optipng-bin, which says I want to use this... but why?

https://github.com/imagemin/optipng-bin says "You probably want imagemin-optipng instead" but I don't see anything that shows this can be used as CLI utility.... why should we want to use this?

I guess optipng-bin is low-level package that is not recommended for direct use. This package looks like user-friendly wrapper for optipng-bin.

Guesses don't help people understand why they're being told to switch package. Low level is fine for automated cleanup, so the original question remains: why is the readme.md saying what it says?

optipng-bin is a low-level module, and imagemin-optipng provides a nicer interface by wrapping optipng-bin. Which we want to use depends on our use-case, so it says "You probably want imagemin-optipng instead."

Right, but this is an npm package, hosted on github, and uses signaling akin to what people use to indicate that a package is deprecated. Rather than saying "you probably want to use X" (which in the context of an npm package has come just be a polite way to say "stop using this") it would be better to add a heading an one or two paragraphs that explain when you want to use optipng-bin, and when it makes more sense to use imagemin-optipng.

We use it for CLI cleaning of PNG files, for instance, where we definitely don't want a more elaborate interface.
