One thing that always gets brought up is the datatypes API. I never got to experience it first-hand (as my username suggests, I'm more of a C64 guy). But the idea is that different types of media are handled independent of applications.

So something like Deluxe Paint could load a PNG by asking WarpPNG.datatype to parse the PNG file and return an IFF (the default data format for audio & video on AmigaOS). If it wanted to display the PNG without modifying it, Deluxe Paint could tell WarpPNG.datatype to display the file at (X,Y) at (Width, Height) and it would get rendered without any special code being added to the application.

This future-proofed applications. Imagine if Photoshop, Chrome, Preview, and Pages could all work with webp images as soon as you added a library and it registered itself to handle "pictures".
