jford,
I certainly see your point and, of course, this is only my opinion! I know nothing official about any of this! If I was PG though I'd wanna confirm whether this is an issue or not before I openly allowed UserTracks to be published that were created straight from a 3rd-party sample library.
Some companies are more strict than others when it comes to how you can use the licensed products. For example, Big Fish Audio are very strict requiring you to get special permission even for creating a song that will be sold in a library! They almost certainly would not allow their samples to be used to create UserTracks! Here is what they say,
"This license expressly forbids resale, rental, loan, gift or transfer of these samples in any format or via any medium, except as part of a derivative musical work. This license does not allow you to include the samples, whether unmodified or as part of a derivative work, in any music library or sample library product."
