Why should Firefox support plug-ins at all, if not to compensate for a lack of features? Why should Emacs support scripting, if not to compensate for a lack of features?
The point is that we enjoy FF plug-ins and Emacs scripts because they allow us to customize these "featureless" products to our individual needs. Similarly, I welcome plug-ins like Linkification and Scriptmonkey because they allow me to customize websites to my individual needs.
I would be surprised if this were the only website that you would find the Linkification plug-in useful for!
