since it's the 'best' practice, you have to tolerate the existence of 'better' practice and 'plain' practice. remember openSUSE is not a KDE-only distribution. please be sure to have all the contents in chapter "support in wayland compositor" read, then talk about 'balanced' practice. in my opinion, the 'best' practice is to have all DE openSUSE support work, not to satisfy any single one.
