I get “irrevocably bricked system” from the fact that they “broke their system” and I am inferring it could only be something worth mentioning if it were irreversible.

I originally was trying to point out that parent was off-topic, because :x and :X are different. But a fleet of downvotes flooded in, so I defended my viewpoint for the catharsis.
