The depth default would still be unbounded if not set explicitly.

>From RFC 8040

    The requested data node has a depth level of "1".

So, a request towards /restconf/data would yield depth level 1
on /restconf/data, /restconf/data/node would be depth level 2,
and so on.

If the request would be towards /restconf/data/node instead,
/restconf/data/node would be depth level 1.


> is the "depth" default still 2 for "/restconf/data" if there is a
> "field" query operator?

If depth and fields are combined, nodes that would be selected
in fields (and all ancestor nodes) would have a depth value of 1.
I.e. the path to the selected node is included even if depth is
lower than the nodes included in fields. Otherwise the depth
query parameter is obeyed.
