Yes. The point is that software is not static. I work on mobile app that doesn't really have the scaling issue, but it's not that uncommon that a new OS update or phone model has new bugs that needs to be worked around or changes some undocumented behavior that the app accidentally depended on. It's not that difficult from mechanical wear.

In a previous job in early 2000s they did have some legacy software that was originally written for VAX/VMS and run on an emulator. Even that environment wasn't stable enough so they maintained some real VAX hardware just in case. And as far as I know, the hardware was physically breaking down.
