I imagine adding coffee to the boil would create some undesirable bitterness.
Once I read an article that said that the flavors in coffee that taste good are released at just below boiling, like 211.9 degrees. It further pointed out that the bitterness of the coffee bean was released at boiling temps and above. Since then I've been using a coffee press and my coffee is never bitter.
Something to think about.
