Has there been an official statement regarding this yet? I know there is still some disagreement on whether the Sutured Ghoul checks only at the time of removal, or if it checks constantly. Basically, the argument was whether it works like it did in the Judgement FAQ - which is the way Dracoplasm works with a very similar effect - or if it works the way judges seem to be ruling, that it continuously checks. This would mean that a single Goyf could be Pull From Eternitied to kill the Ghoul if it's the only card removed to it. Last I knew, it was working its way up the chain for an OR. Have you heard anything?
This is how Sutured Ghoul works, as Offical as it gets. The information from the Judgement FAQ is not correct. For whatever reason WotC does not update old FAQs when rules change, so over time they may become obsolete. (The Ice Age FAQ speaks of making a counterspell target itself, the Saviors FAQ says that Evermind can't be played under any circumstances).
Dracoplasm, on the other hand, is a bit messy. As worded it doesn't exactly "work." This will be fixed with the next oracle update. Dracoplasm does have it's p/t locked in when it comes into play, and that functionality will likely be maintained in it's new wording.
As for "working it's way up the chain," I can tell you that I myself am pretty high up on that chain. I do make mistakes, sure, and will be certain to correct and acknowledge those mistakes as soon as I become aware of them. Also I will acknowledge it in the thread if for some reason I'm waiting on some other source for an answer (search through previous posts I've made and you can see where I've done that). But absent either of those, you may rest assured that my answers, when it comes to rules, are Official.
