In BFO, where I work, this would make it a dependent continuant -
can't have a hole without it being a hole in something. (02)
I also agree that this is distinct from nothing, which isn't
anything. Seems better to have "nothing" mean nothing, and instead
focus on naming and characterizing the things that one tends to refer
to when overloading the word "nothing", like holes. (03)
