Not exactly. It's not a "users" choice to use an old build. If they had a choice, they would certainly prefer the latest version. Old versions keep being ported because there's a pre-existing source code which is more portable to different devices/OS's.
The most annoying aspect in this situation is that old romsets keep floating all around the web and they won't disappear because of such old builds, which require old romsets to work.
