         pause post-kernel, pre-initrd, Press any key to load initrd

         pause post-initrd, Press any key to finish booting

    In legacy Grub, above is valid. Pausing between the two operations helps one
    estimate loading times of today's relative giant kernels and initrds that
    take can considerable time to load on older hardware. I'm having no luck
    finding an equivalent for Grub2, or to even just to display some message
    to indicate they are loading without any pausing, instead of just a black
    screen from having made a selection until kernel messages begin to appear.

Nice! Thanks! :)

The reason instigating my interest in this area was loading delays, begun 
nearly 8
years ago, and described here:
