I still find it absolutely ridiculous and extremely unlikely, something that you shouldn’t have to account for. I can understand breaking an iPhone screen since you carry with you at all times.
It is like comparing and shopping for a car based on whether it will accidentally catch fire. Unlikely and there more things to worry about than breaking your monitor screen.
It would still be possible for you to break your screen through one minor accident. If you rely on your computer, the possible emergency repair costs should be considered before purchase, even if it's unlikely.
How many computer geeks don’t have at least one spare computer around? For me, all my development is cross platform. If push came to shove, I would setup a VM on AWS and use the Workspaces client for my iPad.
Of course if you’re doing iOS/Mac development the situation is different.
