I won't usurp Randy's joy of explaining the rationale, but in general, 
filesystem extensions cannot be considered complete without hooks for all 
the primitive functions, because otherwise the hook won't be transparent.  
The primitives include dup2, link, unlink and others.

As for the bloat, where do you see it?  If you don't install any of the 
hook, the only bloat is that the low-level functions test whether they 
were installed or not.
