[wix-users] SuppressDowngrade still installs a bundle

[Bob Arnson]

The intent behind the feature was to allow an ISV to ship a redist and not have it fail if the user already had a later redist installed. It was originally introduced for the VC++ redist.

That documentation doesn't match the commit message (
https://github.com/wixtoolset/codeplex/commit/2222d3e0e988763b3a46d07583acfd5046949e36
):

Add bal:WixStandardBootstrapperApplication/@SuppressDowngradeFailure to let attempted downgrades happen. This is useful for redistributable bundles where a later version major-upgrades prior versions and where a product that ships with a prior version shouldn't cause an error when a later version of the redistributable is already present.

Why do you want your bundle to return success if someone tries to install an older version than the one that is already installed? Don't you want the user to know that it failed to install in that case?
