Yes, basically my philosophy is only to list in world the actual programs I want to use. Everything else required for them will come in automatically (assuming I also set my USE flags in package.use properly). Some packages have optional run-time deps, say a multimedia program that can convert files if you have ffmpeg installed, so in those cases those optional packages will also be in world. Learning when to use --oneshot and when not was the key to keeping away the clutter :)
