Checking before the operation would allow any script to verify whether the publisher was reachable and exit gracefully with a "Network is unreachable" message. This is a very realistic scenario.
Yes, however, network operations can fail for a variety of reasons and at any time so attempting to determine if failure will happen before the operation is executed is not the correct solution.
The packaging system already provides appropriate error messaging for the failure cases. If that failure messaging is inadequate or needs improvement, please feel free to file a request for enhancement through the appropriate support channel.
Otherwise we get "Installing", "Failed", (figure it out) "Network is Unreachable" and a much more unpleasant user experience. Our methodology is to do all possible to guarantee that an action will succeed before we attempt it. It's the same as checking whether a packages dependencies are there instead of installing it to find out what is missing.
So what happens when you check that the network is reachable before you execute the operation, and then a network failure happens later during the operation? You've just moved the point of failure without actually improving the user experience.
As I said above, the packaging system already provides the appropriate error messaging and handling for this scenario. If you feel that it needs improvement, please provide specific feedback as to how.
