ability to remove command from bundle

I have noticed that when I register an existing bundle to my project sometimes I get new commands (app/console). The problem is that as project grows and new bundles are imported I get more commands more. Some of them I want change which is fine just by overwriting but there are also useless commands and I want to get rid of them.

Would you consider this as something missing in symfony2? or am I missing this and its possible?
