I think SCP's deletion has been a long time coming. I definitely think the supporters have done their best to make SCP as coherent and comprehendible on the wiki as possible, but the problem at the end of the day is that there's no "right way" to do it because of how the verse functions. You can't just do "Article Canon" because even the articles alone can often link to stories that fall outside the idea of Article Canon, which are already connected to a ton of other stuff that are also outside the article (such as with SCP-105, who isn't on the wiki, but is a good example of this). Extended Canon is incredibly dubious because there's tons of different stories and continuities that contradict each other in the context of the original articles and outside of it. The site themselves says that the writer can make The Foundation as capable or incapable as they want to. This is already a problem for guys like 173 and 682, but are an even larger problem for pages like The Foundation itself. I'm sure everyone's heard this before, but its true. You can't convince me that the same group that can casually contain Tier 1-A menaces also logically struggles when a dude who's biggest claim to fame is "snapping necks real good" gets on the loose, because there's tens of different writers across the web giving their own takes on this, and unlike a group like DC or Marvel, they aren't part of a larger company that at least has some level of grasp on the story and cosmology as well as official authority. SCP has a lot of fun stories and characters, but its not meant to be looked at through the lens of straightforward continuity. Anyone who contributes to that site and knows what they're doing's gonna tell you that nothing's really canon, you just sort of write what you want. Totally fine on a site like that, not really applicable to what VSBW tries to accomplish
So yeah, I'd say deleting the verse in its entirety off of VSBW is the call to make
