With Internet rumors like this, I think it pays to think about what it would take in practice for this to actually work. So, like Financial Aid is sending out IDOC reminder emails, but Admissions then . . . sends them a list of applicants where it says “don’t bother reminding these people”? What if they make late adjustments to their admit list? What if Internet rumors swirl about what it all means?
The far, far easier thing to do is simply let Financial Aid email everyone, or possibly everyone who is showing incomplete, not try to instruct Financial Aid who they can safely ignore now.
And so on. I think sometimes people implicitly treat these colleges as if they had just one person sitting in a room considering one application and making decisions about how to communicate with that applicant individually. When you realize this is instead a huge operation with multiple different offices trying to handle often tens of thousands of applications, the idea there is some great individual significance below the surface purpose of any given communication falls apart.
