That surely doesn't make life any easier for filesystem developers, I
agree. From that point of view, all telldir cookies should end their
life at closedir time. For "rm -r" it would be sufficient if the nfs
client simply didn't seekdir at all. For "ls -lR", this would return
duplicate dentries.
Please go read the NFS spec. The only thing an NFS client has in order
to read a directory is a READDIR operation that in essence takes a
filehandle and a cookie as its arguments. Unless the server is able to
return the entire rest of the directory in one RPC reply, the client
needs to send a second READDIR operation with a cookie from the previous
READDIR operation. The server is expected to return cookies for _each_
entry in the directory.
That is a protocol limitation, not a client limitation.
