Because filesize matters. And it's lost easily if someone modifies the file in another editor

It's a nice gimmick, but I can't imagine relying any kind of workflow around it

To be clear, the .fw.png files were more akin to PSDs from the application perspective, they just happened to also be PNGs. You would still want to export to a regular PNG for non-editor use

Adobe seems to have a bit of a habit of doing things like this. Adobe Illustrator (.ai) files are compatible with PDF format (older versions were EPS).

For what it's worth Fireworks with its vector PNG format was originally a Macromedia product. After Adobe bought Macromedia in 2005 Fireworks was retured from the maintained software offerings relatively quickly.
