I would be happy to see NFSv2 go away. However, depending on how people 
their diskless root fs, they do end up using NFSv2 for their root fs.

Does booting over NFSv3 affect this?

I think the answer is no for a FreeBSD server (since the NFSv2 File Handle is 
the same as
the NFSv3 one, except padded with 0 bytes to 32bytes long).
However, there might be non-FreeBSD NFS servers where the NFSv2 file handle is 
than the NFSv3 one and for that case, the user would need NFSv2 boot code (or
reconfigure their root fs to use NFSv3).

To be honest, I suspect few realize that they are using NFSv2 for their root fs.
(They'd see it in a packet trace or via "nfsstat -m", but otherwise they 
  think they are using NFSv3 for their root fs.)
