Yup, the regular Booleans are same as they were - this is just an extension to them for the case where face sub-objects are selected.

Previously booleans just did not work at all when only faces were selected, they worked only on an entire object selected.

I think I'd still like to add in something for "depth limited" booleans when using curves as cutting objects, but I think this method of limiting by face selection will probably be more convenient in many cases because there's no options to set, just make a face selection before doing the boolean.
