FWIW upstream Plasma developers are not super attached to the Plasma splash screen. It mostly exists for reasons that are technical rather than aesthetic: It hides the fact that the parts of Plasma load at different rates. Without the splash screen, or something similar, slow systems will load the individual pieces of plasma (wallpaper, panels, desktop icons, etc) one at a time, making for a somewhat disjointed experience.

Work is currently being done upstream to improve this such that it might be possible to remove the splash screen and not suffer from the above-mentioned visual glitches. The work is scheduled to land in Plasma 5.18. So I think it's quite sane to suggest disabling the splash screen in that timeframe.

No, I mean the KDE Plasma splash, not plymouth. I forgot about the fact that Plasma essentially had 2 and was only thinking of the Plasma effect version.

I think it is VERY important to not display GRUB data to users because that would make some people think something is wrong or that we are going back to 1997 so in this I agree.

On the other hand if you mean the Plasma Splash Screen, as in System Settings > Startup and Shutdown > Splash Screen then I am willing to play with it to test timings.

Yes, KDE Plasma's Splash Screen is what I am referring to. I think this feature only activates after the desktop starts loading elements and I personally turn it off because it gets me to the desktop faster and allows me to do stuff while other elements are loading rather than having to wait for everything to load prior to being able to do anything.

Thank you very much for the feedbacks, packages are being copied to the regular backports PPA right now.
