From my experience script examples usually indicate what version they were made for and add-ons have to declare the minimum supported Blender version in their `bl_info`, which tells what API version it was implemented for. I know that at least on Blender's Stack Exchange the community tries to provide updated answers if anything relevant has changed in a new version.

I can see that older scripts for 2.79 and earlier may cause the issue you're describing, but this doesn't seem like a Blender specific issue. How did Maya handle API changes between versions? I would assume that there were breaking changes at some point that caused similar issues.
