My work-issued 2015 MBP actually started bulging a few months back, so the friendly folks in our IT department replaced it with a 2018 model (with the sucky keyboard, unfortunately).
The first sign of trouble (aside from a slight drop in battery run time) was me going "Why is my laptop rocking back and forth when I type?" (it would no longer lay flat on the rubber feet since the bottom cover was bowed out slightly).
