To my knowledge without "dist-upgrade" and unless specifically asked to
by using "remote" or "purge", apt never ever removes packages.

Just *don´t* do it then.
I know, but it wasn't me... the user just clicked YES to the updates suggested by KDE package updater. I thought its suggestions came only from "apt-get update"-able, not dist-upgrade.
By the way, the reason he updated is that sound wasn't working anymore (only "dummy output" instead of onboard card).
