At least on my system writer is 19 mb, impress is 11 mb, and calc is
24 mb, while the core is about 120 mb.  So the individual applications
are anywhere from about 10% to about 2% the size of the core.
Together the individual applications are about 85 mb.  So yes, they
are less than the core components, but I wouldn't say they are
insignificant.  You could cut out about 40% of the download size if
you just wanted some of the smaller components.
