You need a component to have an individually serviceable element because the decision MSI makes on whether or not to update/repair a file is based on a component's keypath. If you have more than one file in a component and you want to patch the file that is not the keypath you will be forced to include an update to the keypath file. If you have more than one file in a component and the file that is not the keypath needs repairing (user deleted, corrupted, etc) there is no way to do it. In addition, if you ever want to ship the file in a separate installer you must ship the component in its entirety; not doing so breaks component reference counting. If, for instance, you took a file out of a component that wasn't the keypath, shipped it in another product (using a different GUID since the keypath changed), uninstalling the new product would remove the file, leaving the original product broken.
