Overly cautious? Has there ever been a bug report related to corrupt
packages?
A simple size check would detect truncation.

Always.

Or, when using alternative techniques to download, in order to gain
scriptable control over what is downloaded.

I use a shell script to wget setup.bz2, unpack it, compare its timestamp
with my current setup.ini, and tell me whether it has been updated. Then I
use Michael Chase's clean_setup.pl (with local modifications) to produce a
list of URLs to feed to wget. Then clean_setup.pl again to file them into
the correct places in the directory structure.

This makes it easy to maintain a complete set of Cygwin packages _excluding
[prev]_, with an exclusion list by package name, if so desired.
