For one thing, we already have people asking for more than 4 GiB worth of 
initramfs, and especially with initramfs that huge it would make a *lot* of 
sense to allow loading it in chunks without having to concatenate them. I have 
been asking for a long time for initramfs creators to split the 
kernel-dependent and kernel independent parts into separate initramfs modules.
