Let's also summarize what do we have now and what do we want.

This is addressed by the current pathc.

Do you know warnings that have config options? Does this make sense for this featre?

Does that make sense to be able to add aliases to warning aliases? I

I think this is just technical and this does not really affect the users.

I think this might be a good idea in general. @leanil could you address this point in this patch?
