This makes uploaded bits smaller, right? By how much? |

Yes, added the numbers to the PR description. It's ±100KB smaller.
This PR is a no-op for apps (other than making CanvasKit's size smaller). The web engine has been using the browser TL;DR: Flutter web apps today in Chrome are already not using the Skia decoders. This PR is removing the unused decoders to save size. |

There was a problem hiding this comment.
That was the first thing I tried :)
It doesn't work because the configuration object is initialized after skip is evaluated. The configuration value is initialized in a setUpAll callback, so the only reliable place to get the correct value of configuration.canvasKitVariant is inside the test body.
