@Kan, I think the list of removals is related to how old a KDE installation is. On my HP laptop (earlier post) that was originally "Indian Summer", there were 5 removals. On a "Patience" system set up earlier this month, there were only 2 removals.
EDiT: And don't assume all removals will eventually disappear. Sometimes sid packages become obsolete and are removed through the d-u.
