I agree. But I think more people are aware of a regular directory mount 
than about the ability to just mount a single file. So from a sneakyness 
standpoint, I like the "oh, btw, I just took over just the one file I care 
about" rather than trying to hide the whole directory.

Doesn't matter conceptually, though.
