LGTM! :)

The only problem I see is that when you add a new plugin, you will have to change two tests. +1 anyway as that might be a good thing.

I also have a question, what happens if somebody wants to name the plugin my_plugin, with underscore instead of a dash?

This would also break if there is another package that puts stuff here, very dodgy, but possible. I prefer the tight control in some aspects. In the end, 'list-plugins' could also just be a fixed list :-P

It is my question too, we would just need some tight control here. This is the inherited design. We can eventually grab the name from an attribute inside the module.
