This all sounds very cool, but would you mind explaining the motivation a
bit? For example, isn't a manifest class itself meta-information about a
package? What does this new feature enable us to do for/with classes and
packages that we couldn't do before? Thanks!

I thought I explained it in my blog. But I know that I am a bad writer.

For Commander examples look at github https://github.com/dionisiydk/Commander/tree/dev. It's still draft and not full.

About packages It was just an idea.

Yes, Manifest is a meta information itself. But you are not able to extend it from different packages like class extensions. I don't know where it can be needed. But with class annotation approach you can do it.

Actually it is the main feature required for Commander: UI packages extend commands from domain packages with information how to access and execute them from UI. It makes commands reusable.
