Well I thought about 


(as the documentation of source3 says that \hbox_unpack_clear:N is

And as I can see l3galley uses 

  \tex_unhbox:D \c_empty_box.

Is there any real difference between the three variants?

And is the name in l3galley "\galley_leave_vmode:" stable? I would
prefer a standard command instead of my own local
\leavemode-command. \leavemode is imho such a central concept that
it should have a standard name. 

I wish you all a happy new year!
