Earlier, there were things like kde-standard being removed. Now the list for me is
kdepimlibs-data kdepimlibs-kio-plugins kf5-kdepimlibs-kio-plugins knode
libkf5composereditorng5 libkf5gapiblogger5 libkf5gapicalendar5
libkf5gapicontacts5 libkf5gapicore5 libkf5gapitasks5 libmessagecomposer4
libmessageviewer4 libtemplateparser4
I'd advise some caution.
