The current packaging model is one massive binary per version -- it eases
the task of maintaining packages (which, by the way, is done by
volunteers). If you'd like to push for a change, you're welcome to (it's
an open source project), but that's a very big undertaking (involving,
among other things, changes to setup.exe). Interestingly enough, there
was a proposal at some point to do exactly the opposite - maintain one
huge binary for the whole of Cygwin instead of separate package files.
Reading that thread might be useful.
