Flicker-free boot can help you too—it's not a synonym for concealing the boot process. Wouldn't it be nice to watch the text logs progress tidily as the graphics drivers load? "Flickers and visual disturbances" can disrupt your ability to read potentially important boot text.

The level of disruption can vary greatly depending on your particular hardware; some external monitors take multiple seconds to show an image after the display mode is changed.

I agree with another comment that said they want the pretty picture when it works and the text dump only when something has gone wrong. The best of both worlds.
