I don't think that is correct. When you start the installer with an existing version still in place, the first thing it does is to call the uninstaller to remove the previous version and supposedly restore the backups. So what the installer then saves is the original file.
Of course this does not mean it cannot go wrong. But not as easily as you describe. Maybe there are problems when the install is interrupted or crashing, or when you do things that the installer does not expect (like using another package management system to update files that the nvidia driver also affects). The installer will put error messages in a logfile in /var/log when it detects such problems.
With kernel updates, there are always the same problems with closed drivers. I know that every time I upgrade the kernel I have to fiddle with the nvidia driver and VMware. But I never had to buy a new computer to fix it.
