For me, a full-upgrade told me that
The following packages will be REMOVED:
akonadiconsole akregator dolphin dolphin-plugins k3b k3b-i18n kaddressbook kate
kde-baseapps kde-plasma-desktop kde-spectacle kde-standard kdegraphics kdepim
kdepim-addons kdepim-themeeditors kinfocenter kmail knotes konq-plugins konqueror
konsole konsole-kpart kontact konversation korganizer kwin-addons kwin-common

libkf5messagecomposer5abi1 libkf5messageviewer5abi1 libkpimimportwizard5
mbox-importer okteta pim-data-exporter plasma-desktop plasma-widgets-addons
plasma-workspace yakuake
which didn't fill me with confidence. More than usual, I suggest you check when upgrading. It might all be very temporary.
