Distros generally ship the version of upstream that is maintained - that is the one that when you report a bug against it the bug is very likely to get fixed and posted in a new release.
Once 3.5 was abandoned, distros basically had little choice but more to 4. So then to say that it was only a beta/etc is a bit disingenuous.

KDE 3.5 was never abandoned. But it's true that most app devs got lured into the upgrade lure. 3.5.10 was relased in august 2008, when 4.1 was already out, and 3.5.13 was release as Trinity last year.
