Render a splash screen before game loads.

Some games may take time to load before they show a window. (Rounds on Steam is a awfully good example)

It would be really useful if Gamescope made sure there was a window as soon as possible so that the game will not end up stealing focus later on.

I believe Gamescope already does this, but I think because Wayland compositors such as KDE will not show the window until the first frame has been buffered, it will eventually steal focus at an annoying time.

I believe the fix is to simply render something to the window buffer so it can be manipulated and it won't steal focus when the game loads.

It could just render a solid colour, but it could also include something useful such as the executable name.

I would bet there are plenty of other games that would benefit from something similar. Even a few seconds of waiting for the load can be annoying.
