If it hits a sweet spot between size and speed, it may be interesting.
Optimally, you wouldn't need a boot splash, but for cases where you have one,
you don't want to delay the boot process any longer. I guess it currently
looks like this:

  CPU usage: png > qoi > bmp
  IO  usage: bmp > qoi > png

So there's a case to be made for its inclusion.
