Yes, that's fine. You can do any type of upgrade/patch if you're just
rev'ing a component's resources.

No. The easiest way to think about it is that a component is immutable
(at least once it's shipped). Adding resources violates component rules.
You'd have to do a major upgrade that completely removes the old product
before installing the new product.

You can add components and features in a minor update as long as you
don't move components to different features or change the layout of the
feature hierarchy.

Yes, the Upgrade and UpgradeVersion elements control the Upgrade table
which MSI uses to support major upgrades automatically.
