Interesting, could we deprecate implicit filter without deprecation of
unnecessity of parameter? As actually, it's good when this parameter
is not necessary, in most cases user is not interested in node-name.
A modern client is supposed to be interested in node-names. We basically
expect it to manage the whole block graph at a node level, so it should
certainly make sure to know the node-name of every node. It will need it
to take snapshots, insert filter drivers or anything like this on top of
the implicit node.
So once we make the option mandatory (which means returning an error for
legacy clients that don't do node-level management), I don't see a good
reason to ever make it optional again.
