Plasma 6 proposal: disable splash screen by default
The splash screen from ancient times was used to make people less anxious during the long period of a login process.
But since Windows has become almost unusable with HDD, SSD is popular nowadays. The splash screen on the contrary increases the loading time from entering password to the desktop finally being shown, brings negative performance hints about KDE Plasma. It's time to disable splash by default, and perhaps even remove it completely in Plasma 6.
