I agree; it's because of technical reasons that it makes no sense.

What it's "critical" in the *general case*? It's NFS "critical"? It's
bluetooth "critical"? It's the network "critical"? It's LVM
"critical"? Are you going to put all of that in /boot or in /?

An initramfs covers all those cases (and many more). It doesn't matter
if some really simple cases could
possible-perhaps-if-the-stars-align-maybe work; the devs cannot
complicate the general case just to keep supporting some simple cases.
The devs want a *GENERAL* solution, that works for everybody.

That solution is an initramfs.

Regards.
