I'm slightly confused as to why this requires the installation of various binaries when PHP GD natively supports webp as it is?

This is the minimum amount of code required to convert a 1.5MB jpg to a 300KB webp:

$image = imagecreatefromjpeg('/path/to/sample.jpg');
imagewebp($image, '/path/to/sample.webp');

That right but webp provide more options especially lossless while converting images.

You do not need cwebp to create lossless WebP

GD in PHP 8.1 will support this:

imagewebp($image, 'image.webp', IMG_WEBP_LOSSLESS);

and and it is already possible with ImageMagick.

$imagick->setOption('webp:lossless', 'true');

Does this addon serve webp images to browsers that support it and original format to those that don't?

No. It’s replacement.

Well. With cwebp it work every version of php.

Some ~5% of browsers still don't support webp, so simply replacing all images with webp variants is not a good idea...

WebP image format | Can I use... Support tables for HTML5, CSS3, etc

caniuse.com

The webp replacement should only be done when the browser sends that it accepts it in the request, something like the following should work:

if( strpos( $_SERVER['HTTP_ACCEPT'], 'image/webp' ) !== false ) {
    // enable_webp_serving();
}

It’s trade off. With webp and lossless you save a lot of storage.

In the case you want to support old browsers you may save 2 versions of image (webp and original) which intense your storage or decode while serving images which intensely cpu
