A question: Why not use root=/dev/nfs and the other options

kernel doc, like nfsroot=... and ip=autoconf? For me that is much more

It is a matter of taste and historical contingency, I suppose. The
current nfsroot mounting stuff was added way before initramfs/initrd was
an option, and it was probably easier to not mess up the in-kernel root=
handling code (which expected a device to mount).
I think it is important to keep backwards compatibility in this
specific case, and handle "root=/dev/nfs" kind of stuff. Really, think
about keeping 2, 3 different cmdlines depending if the system is newer
or older. It may look like a small hassle, but getting this right
sometimes takes some time
Who's tools handled "root=/dev/nfs"? /dev/nfs cannot be a valid dev node?
That's an in-kernel implementation, or for user-space a hint that there
should be a nfsroot cmdline optione.
