I specifically search out the kernel option to pass in grub2 to see the dmesg scroll past in text during boot, so I think I am the opposite of people who care about flickers and visual disturbances during boot.

More than once having the kernel boot visible has helped diagnose hardware failure or other OSI layer 1 issues with the system.

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.
