From a purely bi-partisan viewpoint, I think this is a big deal for many other reasons as well. If I remember correctly, a few Republicans defended Sessions saying that his firing would cause some backlash. This was due in part for their admiration of the man as he gave up a Senate seat to become AG and for being a pretty staunch Republican. On the left, Sessions is known to be the leader of all the big police/drug/immigration policies that the Trump Administration wanted enforced. He also was a piece of the puzzle between Trump himself and Mueller like you stated above. His ousting definitely has feathers ruffled on both sides from what I can see.
