Ignoring your supposition that Glove of Darth Vader fits into the "old sources" category, and is therefore S-canon, the Glove of Darth Vader series has been referenced in most if not all of the latest Essential Guides and the Complete Star Wars Encyclopedia. Are those sources just not good enough to wrangle them in as "official" for you? And besides, how exactly do you reconcile the fact that the Marvel comics were reprinted by Dark Horse "after" the Holocron was created? Do we just pretend that those reprints weren't accounted for by Leland? And your main qualification for S-canon has been, "published before the holocron". These reprints weren't, so what's the deal here? The logic just doesn't hold up in this, and many other, cases. Also, that reprint made them more available to a wider audience, which is one of Leland's qualifications for whether a source falls into either canon category. Additionally, how do you understand the issue when many of the comics have been reprinted for those action figure comic packs? Wouldn't that make those particular comics "C-canon" by your definition? Yes, Leland did address the Marvel comics specifically as S-canon, but that statement was years ago, and how do we know that he wasn't just referring to their status at that moment, rather than "for all time", as you seem to believe? There are just so many extenuating circumstances with Marvel comics that trying to lay a blanket statement on them is dishonest, and frankly I can't see the motivation in doing so.
