Finally did this. Very pleased with the results but much more of a PITA that everyone made it out to be. Most of my screws were threaded in from above, so I had to remove some screws elsewhere in order to bend enough plastic to allow a ratchet up there. Also, once all the screws are out, you still need to apply what seems like an "I'm about to pull the whole bumper off" amount of force to get all the snaps to come loose.
