Whether they’re on paradox or not, the issue is indeed that people need to maintain those links, which can be a lot of work.
For SW, the difference for 3.0 is going to be much more than simply the resolution. But regardless, I’m sure there will be multiple versions available, just like there are several formats of 2.5.
The issue of archiving old editions is another matter. This Star Wars scene has a strong enough following that private trackers are likely to be a good option, or requesting a someone send it as a favor. People archive old versions of everything, but it’s mostly for a sort of scene nostalgia, or for future conparisons and things like that. Most people would probably agree that subsequent releases are absolutely upgrades and render the old ones obsolete.
Edit: fourth place, no medal.
