I agree that the ADC could be replaced with the GOC without much impact, but I really love Anomalies Without Borders. When I only had the name, I thought "that sounds like a Manna spin-off," but the note makes it clear that they're not much like Manna at all. They're both humanitarian groups using anomalies, sure, but AWB operates on an entirely different scale than the MCF, and largely outside the Foundation's purview entirely. (Which makes "Without Borders" an amusing pun- they're not talking about nations, they're talking about universes…)
The impression that I got was that our reality is neither their headquarters nor the site of any of their relief operations, just a convenient waystation in between. The trains don't open the doors in SCP-2887 for the same reason nobody leaves their car at a highway rest stop and starts walking.
