I'd say it is easy enough, just paste some random scary command from a quick Google search into the shell. Or maybe my expectations are too low. It is not like I could have known how to disable the insanely stupid ApplePressAndHold thing on macOS without searching online...

The problem is the average person wouldn't know what a shell is in the first place, and those are the ones with the least powerful machines that suffer the most from this. They shouldn't have to go through a process that has the possibility of ruining their machine just to get it to work reliably.
