[wix-devs] 3746/4808 - Configuring Bundle upgrades

[Sean Hall]

Looking at https://github.com/wixtoolset/issues/issues/3746 and
https://github.com/wixtoolset/issues/issues/4808, Burn seems to have been
designed so that all Bundles have the equivalent of <MajorUpgrade
AllowDowngrades="no" AllowSameVersionUpgrades="no /> without the ability to
change it. All RelatedBundles with type Upgrade work the same way.

Is there a reason we shouldn't enhance Burn to support configurable version
ranges for RelatedBundles? That seems like the way to go.
