This statement is true for 9P2000.L protocol;
But for older protocols we have standalone servers like spfs/npfs.

No plans as of now; I know folks in the Latchesar Ionkov attempted char 
dev transport.
Not sure the latest though.

No plans yet..and I think this is a bigger discussion.
Being part of QEMU brings few implicit advantages like simplicity in 
sharing, security
and performance advantage. I think taking it out can have its own merits.

If there is enough interest I am sure these two are something we can 
look at as a community.
