WebDFS uses a stack to maintain a frontier, and recursion uses (or utilizes) a stack to maintain, well, the 'call stack'. Implementing DFS using recursion simply means replacing the stack with a call stack. Since BFS does not use a stack, there is nothing we can replace with the call stack, and thus this implementation feels a bit unnatural. That ...

Level 0 consists only of the source node s. Level 1, same as BFS, consists of all the nodes adjacent to the source node. Those are nodes within an edge of the source, i.e. through a path of length 1.
