Sure but the value of package manager that can't do this mitigates its general
usefulness and adds to the "confusion" factor for people 
installing/updating/removing,
etc.  Given the number of postings on this list which stem from confusion about
the operation of 'setup.exe', the importance of this factor shouldn't be 
underestimated.

Sure but it is another issue where lack of symmetry is likely to cause problems.
Those used to using rpm or other package managers on platforms where this is
not a strict requirement for upgrading packages will likely be confused or 
annoyed
by the Cygwin's requirement for this.  This, I believe, is less of a crucial 
issue
than the one above.
