Well, it might have been intended, but it didn't work that way. It
worked as if you would pass TRUE. Since you pass FALSE, the behavior is
not the same as in 1.6.x.
And shouldn't the old APIs stay compatible? To stay compatible with the
old APIs, you would have to pass TRUE in that wrapper.
Or am I missing something important here?

Why? If I pass depth infinity, I *want* the depth infinity, not depth
children. If I want the depth of the WC, I can pass depth unknown.
That's what the depth 'unknown' is for: to specify that the depth of the
WC should be used instead. If I pass a specific depth, I want that depth
and not something else.

I don't understand: what exactly are you missing from that table above?
Can you maybe provide me that part of the table, and I'll fill in the
data that's returned.
