What you are talking about in the text above is not an option but something
that is called a "primary" operator.
"primary" operators are evaluated in the expression interpreter, _options_ are
evaluated elsewhere.
-mindepth, -maxdepth, -xdev are options by not "primary" operators.
Mixing options with "primary" operators is ugly.... but it seems to be OK
to let users see that there is such a difference...

...the name -filedepth does not look like the best choice as it refers to the
directory nesting level "above" the files.
