I don't know if I like this tip - there's no guarantee that my bundle has services that start with `acme_demo`. Also, I don't think it's so common - except for big things like SonataAdminBundle - for a bundle to depend on another bundle, and if you're using something like that, I think you are more apt to understand that you can't just remove one of the bundles. So, I think we should move this point (3) down below (4) - it is the least likely to be important.
