Handling this within the package manager would allow for a better user experience. instead of getting the package downloaded, then having to click on a prompt, the package manager could add this prompt earlier in the process. Possibly even having a switch, config file entry, or other means to automate clearing the prompt. Right now, having to click this prompt might be a blocker for large instuttions trying to use software that isn't approved by SmartScreen, and this feature might remove that blocker.
