I can certainly understand where you're coming from here. It really depends on a person's needs. If you only have 4 plugins that you always install on sites (and they're all hosted on wordpress.org) then it's fairly handy to favorite them and bring them in via the "add new" plugins page. I think if you need something far more involved than the options listed here, you might consider writing your own script to handle it. I suspect many people are do this.
