The fact setup is a non-Cygwin application is actually intended goal.
This way it can actually install and, which is more important, update Cygwin.

I call Occam's razor. You are trying to replace a single application, which
already exists and works quite fine with a set of applications, that do the
same, as well as potentially cause a headache to the user, if accidentally
mishandled.
All setup is really need is more APT-like mechanics of package dependency
handling. That's all. What it already does, it does pretty much sufficiently.
Also, don't forget, that heavy part of installation/update process is enclosed
in postinstall scripts, which are run in Cygwin environment.
