I have great respect for the work and effort you've put into this, but 
it just doesn't make sense to add multiple redundant syntaxes of doing 
exactly the same thing.  I accepted it earlier because I was under the 
impression that all of the above were Legacy syntax from kernel's 
nfsroot.txt.  But now I realize it is invented for dracut.

Furthermore it makes less sense to add redundant syntaxes immediately 
for them to be classified as Legacy.

Also,

root=/dev/nfs4 nfsroot=...

How is this a shortcut for

root=nfs4:...

?
