Codeigniter development (v3.0)

I wouldn't consider these simply frilly and pointless. The dash check allows users to automatically map a controller URI segment such as "manage-users" to the actual controller "Manage_users", without the need to add routes for every instance. Since dashes are typically more ideal for URLs and SEO, this is an extremely useful feature.

Route callbacks are a little less useful in the broad spectrum of things, but still offers more flexibility to the routes system. I'd hardly consider ~40 lines of additional code as bloating the core. It also does not impact the standard route functionality. I think that the feature adds more flexibility to CodeIgniter without being complicated or changing core functionality, so why not?
